The Bill series 23

Manson investigates when grieving father Rick Harris appears to abduct a young boy from outside a local medical centre, unaware that the boy is a diabetic and must have regular medication to ensure his blood sugar levels remain the same. With the help of James Tennant, Manson manages to track Rick down to a houseboat which he used to live on – but soon discovers that the boy is nowhere in sight. Meanwhile, Ackland investigates when the youngest of the lottery winning Henderson family, Kyle, begins a campaign of harassment against her partner, headteacher Rod Jessop. Events take a dramatic turn when Rod and Kyle are hospitalized in separate incidents.

CID begin the investigation into the arson attack on the home of lottery winning family the Hendersons. Manson discovers that the fire started in identical fashion to two previous fires investigated by Nixon and Turner, at a foster home and a B&B. Warren Pritchard, the man jailed for the previous two fires, is rearrested after the team discovers he was bailed at trial. Further digging clears him, not only of the Henderson fire, but the previous two, leaving CID back at square one. In uniform, Smithy leads the troops on a search for the car involved in Rod Jessop's hit and run, and it's not long before CCTV footage puts truant Kyle Henderson in the frame for the attack. However, with his brother watching his every move, Stamp and Hollis try to trip up a friend of Kyle's into exposing the truant's involvement. Meanwhile, Meadows and Heaton interview candidates for the new DI post, but Meadows tries to persuade Nixon to apply.

Nixon and Turner's quest to discover the identity of the serial arsonist takes an interesting turn when they discover that Jay Henderson's ex-girlfriend, Cheryl Wilkes, who claims to be pregnant with his baby, has links to all three of the locations where fires took place – the first being her childhood home, and the second being a foster home where she was placed while she was in care. Elsewhere, Smith and Walker investigate after a seemingly minor spat between a market trader and a customer leads to an assault on the customer's heavily pregnant wife, but would the market trader go so far to attack her in retaliation? Smithy asks Walker if she wants to move in after struggling to find a place to live, while Nixon tells Turner and Hunter she'll be the new DI.

Gold and Valentine find a parole officer assaulted and locked in the boot of his car, but the victim may just be a suspect in another crime when his assailant claims he raped his incarcerated wife. Nixon and Masters discover he has been offering sex in exchange for parole, but their investigation takes a dark turn when one of the prisoners attempts suicide. Meanwhile, Hardy witnesses a mugging on his way into work, but discovers that the alleged victim may be heading up a scam exchanging cash for passing marks on the British Citizenship test. After getting injured twice, Hardy takes a shine to St. Hugh’s nurse Tash Niles, who later suggests he moves in with her after the departure of his grandmother to Jamaica.

Panic and speculation swirls around Sun Hill as Heaton reveals the station may be about to close. Hobbs is left furious at the discovery, but Heaton insist the team needed to know before a press leak; Gold, who was notified ahead of time, suspects the super may know more than he's letting on. The suicide of a young mother leads to a loansharking ring targeting vulnerable mothers, so Harman is sent in undercover as a single mother, accompanied by Wright's young nephew. An arrest leads to a sting to catch the kingpin behind the loansharking, but Webb is furious when the deceased mother's ex wades in and blows the OBBO, leaving Heaton to intervene in an attempt to force a confession. Elsewhere, Valentine helps an old friend when his pub is allegedly raided by a man in a chicken outfit, but Roger is disappointed to discover the culprit may be closer to home.

Nadir gets two shocks on his return from holidays as Paul Haskew decides he doesn't need him onside, while SOCA stun him by revealing they know the Colombian deal is happening a month ahead of the time he told them. Using it to his advantage, he gets back in by relaying the info to Haskew, suggesting giving a dummy location for the drop, but his plan could be compromised when he tells barman Chez Williams that he was undercover when Chez introduced him to Kristen Shaw. Furious, Chez refuses to follow Nadir's request - can he persuade him he is bent now when he wasn't before? Elsewhere in Alvarez case, Harman is assigned to a safehouse with drugs mule Eva Garcia, but her relationship hits the rocks when she suggests taking a holiday with a reluctant Fletcher. In CID, Hunter and Turner clash yet again over the suspects in a hammer attack. Turner believes an ex-con is involved, but Hunter believes the woman's son is responsible. When Turner's suspect confesses, he thinks he has the upper hand, but could Hunter's suspect be guilty of more than lying about his lavish lifestyle?

The Alvarez case takes a sinister turn when Eva Garcia's brother turns up at the safehouse. Nadir persists on trying to talk Shaw out of the drug deal, but she refuses. When Garcia's brother is severely beaten whilst confronting Alvarez, the sting looks compromised, with Eva doing a runner from the safehouse after locking Harman in a room. Leaving for her holiday in Tenerife, Harman clashes with Fletcher when he decides not to come, but her journey home throws her right back into work when she finds Eva roaming the streets. Her attempts to lull her back to Sun Hill leads to both women being abducted, and a call from Haskew demanding Nadir at Bar Morocco quickly follows; has he been rumbled? Meanwhile, Perkins investigates a string of robberies involving lone businessmen staying at private hotels, and Hardy finds himself reprimanded by Wright for being heavily hungover at work.

With a gun to Harman and another on him, Nadir is forced to admit he is undercover. As Haskew, Shaw and Nadir dispute on whether or not Nadir is actually bent, Alvarez silences the room by shooting informant Eva Garcia. As Haskew drags Harman and Nadir to the drug deal, Nadir explains all to Harman, leaving her disgusted. With SOCA at the wrong location, the lorry is intercepted with it continuing in the wrong direction, but it is a bust. Nadir proves to Alvarez that the police are going to the wrong place to regain his trust, but he loses Haskew's when he tries to shoot him in attempt to stop Haskew killing Harman. A heart to heart between Nadir and Shaw sees them decide to elope with the cash, but not before CO19 storm the deal and engage in a firefight. As bullets fly and bodies drop, the Sun Hill team are left looking for their own in the casualties.

Nadir awakes from a living nightmare to discover Haskew was killed in the firefight and Alvarez is in custody. He returns home to discover Shaw made it out of the bust in one piece, but both break down over the death of Harman. With Alvarez keeping quiet, Nadir thinks they're in the clear; Shaw subsequently plants a lookalike on Harman's flight to Tenerife to cover their tracks. But when Eva Garcia's body is pulled out of the canal, Alvarez hints at what Nadir has done, and a comment about betrayal makes Heaton and Meadows send Nadir to a safehouse. Meanwhile, Keane and Hardy investigate a burglary and discover that the homeowners were gassed with Nitrous Oxide before being ransacked. Their prime suspect is their former nanny, fired for having an affair with the husband, but his constant arguing with his wife impedes Keane and Hardy's attempts to get to the bottom of the case.

Part One: Nadir comes back to work in a relieved state after Meadows all but admits defeat in their search for Kristen Shaw. However, he is brought back to earth with a bump when Gold reports Harman missing to Meadows, with her last phone call coming on the day Eva Garcia disappeared. And, when the team discover the woman who boarded her flight to be an imposter, a search is duly organised. With phone signals pinging at Bonham Wharf, Nadir panics that he is about to be caught and, after tracking down Shaw, they plan to flee, but his behaviour starts to arouse Meadows and Hunter's suspicions. Meanwhile, Keane and Hardy find a heavily pregnant female at the bottom of a flight of stairs after an apparent burglary, but it appears her partner may be implicated when it is revealed her stolen watch was originally stolen in another burglary, involving Heaton's estranged wife Rhiannon.

Part Two: With Harman's body found and Nadir in custody, MIT swoop in to investigate. Meadows tries to think the best of Nadir and allows him to go home and get changed, but lives to regret it when Nadir slips surveillance, just as DNA proves he was at the scene. He heads off to meet Shaw, but begins to change his mind when he discovers Shaw still has the gun that killed Harman. With MIT and CID trying to track down the runaway lovers, Zain is left battling his conscience. Fletcher struggles to cope when Harman's mother asks to see him, finally accepting that he took her for granted.

All three cases collide when it appears that Collins has a link to prime stabbing suspect Tom Ryan, while Hollis spots Collins on CCTV stealing bandages. Ackland stuns Jessop by suggesting early retirement.

After disputing with Walker over his birthday, they agree to call time on their relationship.

Part One A family event to mark the one year anniversary of Amy Tennant's disappearance is disrupted when her father James gets into a fight with Shelley Fitzgerald, Amy's late mum's best friend who accused him of killing her when she first disappeared.

Nixon seizes the chance to put away a villain from her past after investigating the assault of his ex-wife, who is now running an adult webcam service. A check into her finances reveals she recently had £40,000 deposited in her bank account, which Nixon suspects is some of the proceeds from a securivan robbery seven years previously – but Hunter's impatience leads him to undertake an illegal search of a storage locker belonging to the suspect, where he finds the stolen cash. Meanwhile, Mickey undertakes PR work with the local Neighbourhood Watch group on the Jasmine Allen Estate, but soon finds himself investigating a hit-and-run incident involving the leader of the group.

When Smith and Gold manage to corner him in a nearby park, he opens fire and shoots two innocent bystanders. However, it soon becomes clear that his personal vendetta is against Smithy – and that further targets are on the cards – beginning with Smithy's mother Pauline, whom he attacks at gunpoint.

Turner and Webb investigate an arson attack on the home of an alcoholic, which resulted in his death – but when Turner interviews a possible witness, Heaton is furious to learn that it is none other than psychopathic gangster and former colleague Ray Moore – an ex-copper turned villain who has plagued his career ever since leaving the force. However, a post-mortem examination reveals that the deceased is not the man Turner and Webb first thought. Meanwhile, youngster Jimmy Cunningham is in court to testify against a local thug, Vince Haughton, who violently assaulted a local businessman, leaving him wheelchair bound. However, when Jimmy absconds, it's Stamp and Hollis' job to track him down.

Masters and Hunter investigate the stabbing of a member of the Skens, and Hardy's joy at reuniting with cousin Dominic is quickly extinguished when he discovers Dominic may be involved. Heaton's pursuit of Ray Moore continues when an associate, Paddy Morgan, is shot. Morgan flees the scene and is pursued by Noble and Fletcher; during the pursuit, a young boy is knocked off his bike, and later dies of his injuries in hospital. When Morgan is arrested, he refuses to cooperate and is bailed. CCTV outside the station shows Morgan being confronted by two men, leaving Heaton fearing Moore will have Morgan killed.

Noble and Keane answer a distress call to the home of Ray Moore's neighbour and find Moore's ten-year-old daughter, Annie, threatening a youth with a gun. Heaton suspects that hit-and-run driver Paddy Morgan may have been killed by Moore himself – and that his daughter may have been witness to his death. However, with no body and the only piece of usable evidence corrupted during the earlier armed stand-off, Moore threatens to evade capture again. Meanwhile, Noble and Keane deal with the theft of Annie's bike and criminal damage on a clothes mart – all the hallmarks of an initiation to a long-forgotten local youth cult known as the 'Canley Club', who appear to have resurfaced.

Gold finds herself caught in an awkward situation when Peter Harris' wife Mary turns up at the station with a ransom note – claiming that Peter has been kidnapped. Forced to reveal her night of passion to Manson, suspicion immediately falls on another of Peter's lovers, who arrives the scene of the planned drop to collect the ransom money. However, Manson soon realises that the team have been duped, and it's not long before Gold realises who the kidnapper really is. Meanwhile, a youth is badly assaulted on the Larkmead estate, and with a little help from Niles’ brother, Hardy and Valentine investigate a local youth club owner who they suspect may be responsible for dealing drugs.

Perkins and Masters investigate when a man is found badly beaten in some local woodland, but uncover a strong lead straight from the off when it appears that the perpetrator later made the 999 call which lead officers to the man's location. They discover the victim is an employee of a security firm who has details of a planned delivery of rare and valuable antiques. Meanwhile, Gold, Casper and Hollis investigate a charity scam after one of the donors suffers a heart attack during a botched burglary. However, when they discover that a broken window disguised as the point of entry was actually broken from inside the property, they realise that they may have already found their suspect.

Turner plays a practical joke on Hunter that ruins his investigation into a robbery at a nail bar. When Meadows comes across the pair fighting in CID, he jumps to the conclusion Hunter is the guilty party, and would learn more respect for the job by having a spell in uniform. Valentine is left unimpressed when Hardy ropes him into laborious paperwork to get some background on the mysterious skull Niles’ brother Rudy discovered a few weeks ago, but his hard work discovers a link to an-ex soldier who disappeared after being involved in the Balkans conflict, only to realize their missing man may be a murder suspect.

Hunter squeezes back into uniform and teams up with Kapoor to investigate an Asian girl accused of robbing a shop. However, the victim's racial opinions on the suspect leaves Kapoor suspecting all is not as it seems. Heaton and Meadows spearhead the search for a violent prisoner who has escaped, seven years into a murder charge. Perry and Webb clash over whether to publicise the criminal's identity, but despite early reluctance, a savage assault on a local businessman changes Heaton's mind. Perry is crushed when, after a vigilante attack on the wrong man, Webb cannot resist telling her he was right about his opinion not to go public. With evidence to suggest the brother of the assaulted businessman could be responsible for the original murder seven years ago, Heaton appeals to the escaped prisoner in an attempt to draw him into the open and clear his name.

Fletcher and Casper arrest a member of a gang of steamers who have been carrying out a number of audacious daylight robberies. The boy's young brother is implicated as well, and ends up providing Webb with the information to catch his brother; an undercover operation is set up, but goes wrong when Keane gets stabbed in the arm. One of the gang's victims is revealed as an old friend of Hinckley’s, who drops a bombshell on Fletcher that could be key to exposing Hinckley. Meanwhile, Josh Carey, witness to an assault the day before, makes a startling confession to Wright, and his behaviour gives her cause for concern. Perry is awkward with Heaton following the previous night's encounter – and Webb guesses she has been unfaithful; will he work out who she has cheated with?

Webb distracts himself from Perry’s apparent cheating by investigating a drowning death in the pool at a High Court judge's home. When he comes face to face with Perry, he finds out Heaton was her other man, leading Webb to thump the Superintendent for his indiscretions. When he goes to resign, Webb is stopped in his tracks by Meadows, who gives Heaton a reality check. When Webb clashes with Heaton over a complaint from the judge under investigation, Meadows wonders if the pair can work together professionally again. Elsewhere, Fletcher confronts Keane over allegations that Hinckley’s ex-girlfriend is alive, and after coming face with Lloyd, Keane confronts Hinckley, with disastrous results.

Heaton briefs Gold and Masters on the alleged events the night before at Emma and Matt Hinckley's home. Fletcher is horrified to learn Matt is pressing for a charge of attempted murder against his wife, and sets out to expose the control freak's vicious bullying tendencies with help from former girlfriend Nina Lloyd. Manson organises a raid on a crack house, with Hardy determined to track down the dealer when he escapes. Enlisting the help of the dealer's young runner, things go awry when the boy's mother interferes in the case and is put in danger as a result. Meanwhile, Casper takes pity on a drug addict who takes him hostage during the raid, only for the girl to let him down by falling back into drugs.

Part One- Blood Money: Nixon, Wright and Noble deal with a young woman who was pushed from a walkway on the Cole Lane Estate, and are then called to deal with the attempted suicide of the woman's husband. Further digging reveals the man to be in debt to a known criminal; a sting is set up to trap him, but it goes wrong, resulting in an armed standoff. Wright and Noble are called to a disturbance at the woman's flat the next day, but she has disappeared without trace. Meanwhile, Webb deals with an assault, which leads Perkins, Stamp and Casper to go undercover to trap a confidence trickster.

Part Two- To Honour and Obey: After the discovery of Reshna Dewan's body, Nixon and Meadows wait for the forensic report, which reveals was strangled before being left in the Thames. The investigation reveals she had been having an affair with another man, which leads the team to realise that her in-laws may have been responsible, though which one of them proves harder to find out. Meanwhile, Noble and Webb’s questioning of an alleged mugging victim, Maggie Carpenter, leaves them confused as she throws up several stories that don't check out.

Keane is feeling raw after her marital difficulties boiled over into violence and shows her tough side to new recruit Beth Green, as they investigate a woman's claim her baby has been stolen. Perkins and Masters lead the search for the missing baby. Meadows is anxious to prove he's a worthy DCI, and agrees to go undercover with Nixon to get a lead on the illegal baby-selling business, but his mistake puts his colleague in danger.

Fletcher and Wright attend a disturbance at a family court where a father, Paul Conway, threatens to kill a social worker after punching her in the face. Events then spiral when the social worker is found dead after falling from the roof of a tower block on the Cheetham Estate. When Meadows and Nixon investigate, they discover that Conway lives in the tower the victim fell from, and he is arrested; whilst intoxicated, he confesses to murder. When he retracts this in interview and claims she jumped, despite CCTV footage of them arguing on the roof, Meadows and Nixon investigate the social worker's past to see if she was depressed enough to commit suicide. Elsewhere, new recruit Green delivers her first caution following an affray between a car salesman and a woman protesting against the dangers of 4x4 vehicles. When a TV is thrown through the cafe owned by the woman, she claims the salesman is responsible, but Casper isn't convinced all is as it seems.

Wright again crosses paths with self-confessed paedophile Josh Carey when he tries to jump off a balcony inside the factory he works in. When he states he has been invited to join a child pornography ring, Wright enlists Perkins to help Carey fight his demons and nail the ringleaders. Manson takes charge of the investigation and launches an undercover operation with Perkins posing as Carey. Meanwhile, Hollis and Hunter are called to a funeral home where a valuable necklace has been taken from a corpse in a sealed coffin.

Hunter’s spell in uniform comes to a triumphant end when he borrows a bike to chase a mugger and recovers £15,000 in cash. The case gets more interesting when the victim admits he is being blackmailed. Heaton reassures terrified prosecution witness Martin Turnbull he will be given protection following threats from Ray Moore, only to discover the villainous ex-cop has subtler ways of intimidating people when Keane and Hollis attend the scene of a road traffic accident.

Gang member Wesley Meeks is shot, and Niles witnesses his dying words: the name of corrupt ex-policeman Ray Moore. Heaton struggles to find evidence linking the victim with his arch enemy, but Hardy’s cousin Dominic reveals the red scorpion tag sprayed on all of Moore's properties was Wesley's handiwork. Hunter’s first day back in plain clothes gets off to a bad start, after he and Turner interview a young joyrider, and follow up a report that he plans to take part in an armed robbery. Manson tells the warring DSs about a temporary switch with a Specialist Crime Directorate, and Hunter can't help but gloat when he gets the secondment.

Niles is attacked in the hospital car park, raising the terrifying prospect that Ray Moore is targeting people who could testify against him. Noble encounters a pensioner who turns out to be a fan of Reg's podcast Regflections, and who clearly has other guilty secrets to hide – including what appears to be a series of robberies from the homes of other pensioners. Heaton directs a search for further evidence into Ray Moore's activities.

Following the shooting of her young brother Rudy, Niles agrees when Hardy tells her she now has more incentive to bring down Ray Moore. However, when Rudy’s condition deteriorates to the point where he isn't expected to survive the next 24 hours, Hardy takes matters into his own hands, unaware that the case against Moore is rapidly getting stronger. Meanwhile, Green, Casper, Fletcher and Noble attend a suspicious high-impact RTC. When Green notes the driver wouldn't have been tall enough to be driving, she suspects the woman’s boyfriend or husband could be responsible.

After finally getting evidence to nail Ray Moore for the murder of Wesley Meeks and attempted murder of Rudy Niles, Heaton is devastated by the discovery of Moore’s body at the bottom of a multi storey car park, with the team stunned when Hardy’s prints are later found on a gun at the scene. After visiting the killers and his girlfriend Niles, seeing her agonise ahead of Rudy’s expected death leads Hardy to return to Sun Hill, where he confesses to his crime. However, when the killers are found after fatally overdosing, Heaton decides not to arrest Hardy for his role in Moore’s death.

A frantic search begins for the missing DC when Green discovers a gun has been stolen from the station store by Rachel Inns – and the culprit makes a break for freedom with Masters at gunpoint. As Manson leads the search, Turner and Dasari review her casework hoping for a clue to her whereabouts, but have little luck until an unlikey source provides a big clue.

New sergeant Callum Stone makes an instant impact at Sun Hill by subduing a violent drunk in the station; he investigates the circumstances leading to the collapse of a woman brought in to the station by Casper and Stamp, but his maverick methods instantly alarm Casper and raise Smithy's hackles. Meanwhile, Perkins, Nixon and Walker trace a series of threatening calls made to elderly women back to a single suspect, a supervisor at a kitchen fitting company, who is less than pleased to be arrested in a lift stalled between floors.

Following a report of vandalism on a church, Perkins finds himself investigating a case of assisted suicide in which conflicting evidence from the grieving family members suggests someone has something to hide. Meanwhile, Green and Valentine are called to a pet shop where the owner has been tied up and several dogs let loose, but it's Stone who realises there is something more sinister than youthful high-jinks going on – leading to the discovery of an assault at the home of a drug addict.

Hunter returns from Special Projects and is paired with Dasari, who knows from her colleagues over at SP where Hunter picked up an injury that he is exaggerating about. They investigate a woman who has been robbed of her winnings on the way home from a casino, and suspicion soon falls on the barman who called her a taxi. The case against the man grows stronger when it turns out they also arranged transport for another woman who was attacked, so Keane is sent undercover as a casino punter – only for events to take a surprising turn. Meanwhile, Stone and Casper are called to a domestic disturbance, and uncover infidelity and drug use.

An elderly woman with Alzheimer's goes missing with her great-granddaughter. Uniform run the case led by Smith and Stone, with Nixon and Webb covering the CID angles. Fletcher gets his first FLO case, and just as it seems he's doing well, a blood stained blanket appears nearby. The great-grandmother appears on a dual-carriageway, but there is no baby in sight. Nixon works on her to find the baby, while Fletcher works on the mother, who is arrested when she claims she got rid of the child. It appears she left her daughter at St. Hugh's, but the great-grandmother did pick her up. Fletcher and Casper find the child, but Stone only acknowledges Fletcher's part in the finding of the baby, and Casper duly hands in his resignation when he is offered a security job in Ibiza. Meanwhile, Dasari and Hunter help casino owner Louis Dreyfuss deal with a man blackmailing his wife.

Whilst on patrol, Stamp and Fletcher witness a near hit and run. The hysterical driver claims her husband has been abducted so that men can rob his jewellery store. SO19 storm the building and discover the woman's husband has been shot, and his brother is tied up. CID hunt for the suspects, with Masters and Hunter surprised to see one of the brothers show up at the main suspect's house and attack him. They are both arrested, but the prime suspect has an alibi, and both are bailed. The suspect appears to be closer to the action than they first thought. Hunter helps Monica Dreyfuss when she thinks she sees someone in her garden, and again later when she is robbed and found extremely drunk in a restaurant. Manson clashes with Heaton over an arrest in the armed robbery case.

Armstrong and Keane investigate a missing person's case and uncover a rape. It is believed to be a gang control situation, but the victim won't press charges, so Armstrong tries to convince him to make a statement. He is apparently gay, and it was due to him hitting on a man in a club. Manson coordinates a raid, but the police are shamed by the residents of the estate. Armstrong tries to unite the family when his sexuality comes out, as the victim of the rape tries to commit suicide. Keane completes her probationary period.

Armstrong is surprised when she and Stamp attend an RTC where Perkins recovers the vehicle as a tow truck driver. They learn from Manson that Perkins is undercover to investigate a mother and son duo who are suspected of involvement in loan sharking. When the daughter of one of the drivers in the RTC is horrendously assaulted in an acid attack, Meadows and Manson try to get her father to testify against Perkins’ targets; Green is sent undercover as Perkins’ daughter, and he subsequently learns the targets are stealing cars to charge patrons for repairs to crashed vehicles that aren't fixed. Meanwhile, Armstrong and Stamp help the passenger of the other vehicle involved in the RTC, a Ukrainian immigrant who is trying to marry her considerably older boyfriend to gain citizenship to escape a violent pimp in her hometown. Heaton and Manson clash over methods again and end up having a heated argument outside CID.

Smith and Noble attend to an assault; the victim is stabbed, but the suspect turns the table by accusing her of dealing drugs from her burger van. Stone and Noble thus OBBO her flat, and a man who enters leads them to a house; Gold, back from her leave, sends the police chopper to do a fly by, and heat sources confirm the house is being used to produce cannabis. Stone tries to take credit, which is noticed by Noble and Smith. Meanwhile, Hunter and Turner work on a simple assault involving a former couple, and the girlfriend is now going out with her ex's best friend. The ex-boyfriend abducts his friend, but the case turns out to be a non starter when the friend ends up ditching his fiancée at the altar and reuniting with his friend. Gold makes their day worse by giving them a minor part in the raid on the cannabis factory; Stone reprimands Noble when she is put in danger during the raid.

Part One: Fletcher and Smith deal with a missing person's case. The victim, a 16-year-old girl, is found dead at the bottom of a fire escape. Fletcher is assigned as FLO. Investigation reveals the girl was on a downward spiral. Her boyfriend is arrested due to a serious assault in his past, but the investigation takes a gruesome turn when Fletcher discovers a horrifying video clip given to him by her best friend.

Part Two: Martin Parks is named as the prime suspect for the murder of his daughter Chloe. Her boyfriend, Ben Jackson, is still in custody as Nixon continues his interview. Fletcher convinces Karen Parks to speak out against her husband, and Martin is arrested as Ben's alibi is checked. Just as they seem they've got Parks, he clams up. The verdict determines suicide, and after Parks assaults his wife Karen, Fletcher and Stone find him at the top of the fire escape where Chloe's body was found.

Fletcher tries to convince Stone to tell the truth about Martin Parks' suicide, but Stone tells him "What goes around comes around" and that they wanted Parks to jump. While the events unfold, Fletcher and Kapoor work on several vigilante assaults on drug dealers; when a chance comment from the culprit tips him over the edge, Fletcher guiltily admits to Stone that he was right. Meanwhile, Dasari and Hunter investigate a burglary and assault on Monica Dreyfuss.

After a night of passion with Monica Dreyfuss, Hunter is held hostage by gunmen and forced to rob Louis' casino, with the threat that Monica will be killed if he doesn't comply. He manages to tip his colleagues off, but can't stop the gunmen escaping. Dasari is convinced Louis is behind it, but Hunter thinks the culprit is closer to home. Nixon and Manson contemplate reporting Hunter to the DPS for misconduct, but he goes off to nail his suspect for the abduction and robbery after being sent home by the two DIs.

Kapoor, Fletcher and Stone find a woman covered in blood, above her stabbed personal trainer. Things are complicated when a search team find crystal meth in his flat. The woman is cleared when she says the drugs were stolen from a club owner. A handover takes place, but is nearly compromised, and the owner later denies the stabbing. As they dig deeper it appears that the woman's husband may know more than he's letting on. Meamwhile, after attending an incident at a registry office, Stamp and Armstrong investigate a case of identity fraud involving a British man living in Australia.

Kapoor and Fletcher investigate a string of robberies. She is left unimpressed when Stone forces her to lie in interview after Fletcher tries to force a confession from a suspect by holding him over a balcony. Walker and Green tease Webb and Armstrong over flirtation between the two. They both work on an assault, and make a connection to a domestic incident Wright and Keane dealt with.

One of Stone's informants calls him about an assault on a fellow escort. Kapoor takes them out of the punter's house but as they return to arrest him, he produces a diplomatic immunity card, and he is confirmed as Valatin Turivic, a European embassy official. Kapoor and Stone hope they can get him for drugs, so Fletcher and Stamp tail him. As Turivic hands over the drugs, Stone's informant tells Kapoor that Turivic may have killed an escort. Heaton orders a raid on his home, but time is of the essence as Turivic is flying out of the country. Kapoor is stunned when, out of the blue, she is offered a job at the Foreign and Commonwealth Office, but she is left unaware that Stone pulled the strings to secure her transfer. Meanwhile, Dasari and Hunter investigate the theft of a £20,000 painting.

Turner leads the investigation into the disappearance of two children, and his approach during the appeal sees him selected for a new crime appeal TV show. Perkins is concerned when they see the children talking to a known sex offender. The mother suspects the father is involved. Fletcher is paired with new recruit Ben Gayle, and they deal with an assault. The rookie PC is cornered by three yobs, but Fletcher is surprised when they're on the ground and not him.

Turner launches his new crime appeal TV show, Wanted. He then leads the investigation into his first televised crime, an aggravated burglary at the house of a barrister, who subsequently had a heart attack during the robbery. Hunter clashes with Gayle over the handling of a hostile witness, and their argument catches the attention of the entire CID office, but it's not in vain, as the witness comes forward. As a suspect is arrested, the witness mentions the name of the victim's son, who, on seeing the suspect, disappears from the station. Why is there the sudden guilty conscience?

Armstrong and Keane find a badly beaten woman, who claims to be an asylum seeker whose political activist husband was murdered in Zimbabwe. When her son is found with a bag full of forged passports, CID intervene launching a major investigation. The son is abducted, and it is revealed his violent and vengeful father is not dead, but is planning to take his son home to Zimbabwe. Meanwhile, Gold discovers a bank robber, she believed had died in a bank vault blast she was involved in years ago, is alive and well – and back in the country, forcing her to re-open an investigation into a twenty-year-old bank robbery which nearly killed her.

Gold fights to nail armed robbery suspect Vince Murray, who nearly killed her in the Tozer Street bank explosion in 1983. She enlists the help of her former Sergeant, Tom Ryan, who was paralysed in the blast, but a lack of evidence sees Murray bailed. Meadows authorises surveillance on Murray, and he meets up with the two survivors of the robbery. When they make a hoax armed robbery call, a real one goes down on the other side of the borough - a move that was also used in the Tozer Street job. Armstrong & Webb track down the armed robbers, Murray's son Darren and his best friend Kieran Forrest, whose dad Ian was killed in the Tozer Street robbery. Armstrong lets slip that Vince is alive, leading Kieran to attack her and Darren after realising his best friend's betrayal. When Darren and Kieran escape, Gold tracks them down in an armed showdown with Vince on the wasteground where the Tozer Street Bank used to stand.

Dasari is paired with Masters on her last day at Sun Hill. She tries to connect with a teenager who has a cocaine and eating habit, by giving up her best friend and dealer. Events turn sinister when the dealer is kidnapped by her supplier, and Meadows takes over the case. Dasari tells Meadows she wants to stay at Sun Hill CID, but when Hunter clears it with Special Projects, he is offered a DS post at the yard, and he tells his shocked CID colleagues he's accepted the posting.

Noble and Stone are paired and investigate a fire in a squat on the Jasmine Allen Estate. Masters and Walker investigate the fire. Smith joins door to door with new recruit PC Nate Roberts and they discover one of the victims, Billy McLaughlin, an old army friend of Noble, had a bust up with a local thug, Ross McGuiness. They discover his brother Tam is desperate to find them, but events take a sinister turn when Ross turns up dead in the boot of a car in a scrapyard where Billy used to work. Noble is held by Billy, but Tam shows up, not before badly beating Billy's girlfriend to get his location. Billy confesses to stabbing Ross to death, but Noble suspects he's not responsible. Hunter spends his last day at Sun Hill clearing his desk, and when Nixon is asked to be a reference, he is forced to tell her about the exaggerated injury he obtained during his secondment to Special Projects.

Part One: Hollis is stabbed whilst responding to reports of a prowler on the Aldbourne Estate, but he manages to stop an attack on a local mother, Shelley Cooper. Manson and Dasari lead the investigation and discover Cooper lives on the same floor as a recently released man, Michael Simms, a paranoid schizophrenic that Manson jailed four years prior for attacking a woman. Stone draws reference to Cooper's resemblance to Simms' previous victim, leading to a clash with Manson. Enlisting the help of Simms' psychiatrist, Julia Bickham, Manson's digging leads to Simms being exposed and attacked. With pressure on him, spearheaded by Cooper's ex-boyfriend Chris Ramsden, Simms snaps and abducts Cooper. When her son Jas comes between Simms and Manson during negotiations, a gunshot rings out in the chaos. Meanwhile, Smithy deals with a community leader causing havoc whilst protesting the traffic on the Aldbourne, but later uncovers a shock link to the prowler attacks.

Part Two: Manson launches a manhunt for paranoid schizophrenic Michael Simms after his apparent shooting of Shelley Cooper. Meadows and Heaton run as gold Commanders from Sun Hill, while Manson and SO19 run as silver Commanders on the ground. When Simms enters the office of Julia Bickham, Manson orders an evacuation and guides in SO19. His negotiation attempts fail, and when Bickham cries out, SO19 storm in on Manson's command and they shoot Simms dead. When all that is left is a camcorder, the DPS are called in, leaving Meadows and Heaton searching for the crucial info to clear Manson's name. When Chris Ramsden confesses to the second prowler attack and planting evidence to try and frame Simms, Manson thinks he's in the clear, until the DPS twist things to dig him into deeper peril. Just when it seems like Manson is out of options, Walker makes a breakthrough that could save her boss' career.

Noble attends to a disturbance in her block of flats, paired with Stone. They find a man with a head injury, sustained by an iron. They suspect his wife is at fault, but she is found dazed and confused with an iron burn on her arm. A file shows she previously self-harmed and they suspect she still is. As they go to talk to her they find her overdosing on sleeping pills, and they find an envelope with photos of her with a threatening note attached. Noble believes a neighbour is responsible, but before he is arrested, he and the husband are found fighting in the hallway of the building. As the case collapses, some hard graft and persistence from Stone sees it turn around. Meanwhile, Smithy has to arrest recent witness Carly Samuels for fraud.

Turner and Masters are sceptical when a woman reports her sister missing after less than 12 hours, however her concerns are justified when her sister is found assaulted and raped. When it appears she went off with a famous singer, Billy Peters, they try and track him down. When they do, Peters is assaulted by a friend of the victim, assuming Peters was responsible. Meanwhile, Smith gets involved with the Samuels family again when Carly's mother Leanne is arrested for assaulting a store owner, while Turner befriends the owner of a limo hire firm after he assists Turner on the assault case.

Gayle and Armstrong investigate an assault on a teenager. A fellow pupil, the brother of the victim's girlfriend, is suspected, but he is in Scotland; suspicion then falls on the girl's father who is seen nearby on CCTV. A video is found of the victim forcing his girlfriend to strip, providing motive for the assault, but who sent it out? The victim claims his stepfather is sexually abusing him, but CID are sceptical and suspect the abuse came from the victim's deceased father. His mother dismisses this, but when Gayle and Armstrong call on her again later, they find her tied up, with her son standing over her armed with a hammer.

Part One: Wright and Stamp investigate a suspected racial assault. Heaton suspects that three racists from a supremacist gang, The Bulldogs of Patriotism, are responsible, but Masters is sceptical: she and Perkins subsequently discover the victim was whipped. His wounds and a bandaging makes Masters think that his mother knows something, and she says it was his father who gave the beating. Meanwhile, Noble and Stone investigate a break in at the office of local MP Paul Sagger, but does the assault victim know more about it than he should? Sun Hill later patrol a concert, Rock Against Racism; things turn ugly when Sagger and Nadim Mura, the event coordinator and the assault victim's uncle, are shot as they appear on stage.

Part Two: The team are left dealing with the fallout of the shooting at the Rock Against Racism concert. Nadim Mura gives Heaton a name, Abdul Muntaqim, but dies due to a bullet in his lung, while Paul Sagger survives with a shoulder wound. Ahmed Hassar is questioned but denies involvement, although he confesses he set off a firecracker, which solves the mystery of four gunshots but only three shell casings. Masters and Perkins arrest a hospital porter, a member of the Bulldogs, who might have been responsible for killing Mura in hospital; he is not responsible as Mura's postmortem reveals he was killed by a heart attack, but it's not in vain, as the uncover a conspiracy where the Bulldogs were going to kidnap Mura. Heaton continues the investigation into Sagger's alleged artefact smuggling, but the artefact, an ornamental dagger, which Sagger uses as a letter opener, has gone missing. Dasari makes a breakthrough, and identifies the name Heaton was given by Mura as Haqim Abd Al-Muntaqim; she and Manson go on to discover that Heaton was the target for the third bullet, but, as the DI calls to warn the Super, two bullets go through his car as he takes Sagger back to Sun Hill.

Part Three: Gold runs the scene of the shooting at St. Hugh's. Heaton and Sagger escape unscathed but a suspect spotted by Heaton escapes. Heaton continues the artefact smuggling investigation, while Meadows runs the shooting investigation, and he discovers Sagger's assistant Derek Jacobs may be responsible. The man fleeing St. Hugh's is identified as private investigator, Alfredo Ruiz, hired by Sagger's estranged wife, and he gives CID Hakim Abd Al-Muntaqim's address, but it's too late: Jacobs got there first and Muntaqim is dead. Heaton finally gets the evidence to nail Sagger for the smuggling, but, as the team get ready to transfer the disgraced MP to another station, Jacobs shows up armed with a gun, and with a bomb strapped to himself...

Noble and Fletcher respond to a call regarding a hijacked limousine, which they chase to a building site, whereupon the hijackers flee, revealing a hen party trapped in the back. Matters are complicated when a large amount of cocaine is found in the boot and the real driver's pregnant wife is found assaulted. Turner's driver Trevor Jones helps CID with useful information about a limo operator who is rumoured to be supplying cocaine as part of the champagne service. Webb poses as a city banker to gather evidence against the owner of the limo company, but has a few uncomfortable moments when it look like his cover might have been blown. One of the captured hijackers subsequently claims he was working on behalf of a rival dealer, known only as 'The Postman'.

CID's hunt for the drug kingpin known as 'The Postman' is disrupted when a prostitute is severely assaulted, while Turner's friend Trevor Jones takes a lesser beating trying to help her. A large quantity of cocaine is also found on the woman; her pimp is arrested, but both he and his dealer deny being 'The Postman'. Meanwhile, Gayle and Roberts investigate several attacks on a café and its owners; when a suspect in the case is also found in possession of a large amount of cocaine, he reveals he is working for 'The Postman', but Turner is left stunned when he inadvertently discovers who the mysterious dealer is...

Turner is in hot water following the discovery that his friend Trevor Jones is 'The Postman'. He returns the evidence on his PDA, but when a raid goes down, Heaton and Manson begin to suspect there is a mole in CID. Desperate, Turner admits his dealings with Jones to Masters; the two hatch a plan to trick him into confessing off the record, but Jones isn't fooled. Fortunately, after raiding his limo firm, Perkins, Webb and Walker manage to work out Jones is 'The Postman' themselves; Turner goes to arrest him, but ends up stuck on his boat as he tries to flee the country.

Uniform set up a successful sting on a second hand store; the arrested suspect asks to speak to Masters about people selling him stolen goods, which may be related to a warehouse robbery on a local industrial estate. Another sting is set up, but goes belly up when ram-raiders crash a 4x4 through the front of the store. At first, it appears that the ram-raiders wanted a camera that a woman seen in explicit videos on it wanted it back to cover up her secret affair, but her boyfriend is a villain from Meadows' past, and the team uncover a cash-in-transit armed robbery plot. Meanwhile, Noble and Green discover a computer repair shop scam with a stolen laptop found in the second hand store during the raid.

Part One: Disgraced ex-detective Zain Nadir is interviewed by Meadows about drug trafficking in Hayesend Prison, where he is serving ten years for perverting the course of justice, after Stone and Fletcher discover the body of a drug addict recently released from the prison. He reluctantly agrees to help his former colleagues infiltrate the gang involved, but Meadows is not sure whether he can trust him. He suspects his fears have been proved true when a riot breaks out just as the police move in to arrest the operation's kingpin, and Nadir’s cellmate, Jason Forbes, who makes good his escape in the confusion.

Part Two: Nadir gets a frosty reception at the station when Heaton secures his release from prison to help Meadows with the recapture of escaped killer Jason Forbes. Unsurprisingly, Nadir encounters hostility from several of his former colleagues, especially Fletcher, who can't help taking a swing at the man who callously disposed of Harman’s body in a bid to save his own skin. The pursuit of Forbes leads to a gunpoint showdown, giving Nadir a clear choice between escape and leaving Forbes to kill Meadows, his wife and his lawyer.

Part One: Perkins receives a tip-off regarding an armed robbery from an old informant, and pairs with new DS Max Carter, a transfer from SO19, to investigate it. When a car stolen in front of Armstrong and Gayle is linked to the robbery, Perkins discovers the thief is his informant’s son. When the informant goes in as the inside man, he is sussed and shot by ringleader Jimmy Duncan, and later dies in Perkins’ arms. When Stone and Fletcher attend a report of a drunk man refusing to leave a pub, they find Perkins drowning his sorrows. Meanwhile, Armstrong and Gayle arrest two girls for failing to pay their cab fare; suspecting them of being drug mules, a search of the home of the cab driver who confiscated their bags uncovers a poisonous snake. When their release is delayed, their boyfriends arrive and take drastic action.

Part Two: Armstrong and Stamp are taken hostage at gunpoint and dragged to custody, where Gayle and Wright are also drawn into the siege. When an SO19 officer is shot by the getaway driver, Stone and Fletcher alert IBO to the incident. Heaton and Nixon spearhead the negotiations, while Gold liaises with Wright, on behalf of the gunmen. As they release a hostage, fellow prisoner and armed robber Jimmy Duncan cons a rookie gunman into handing over a gun and shoots him dead. Perkins awakes from his drunken stupor to the siege, but upon discovering Duncan is leading it, tries to get him on side to avenge his informant’s death. If he can get Duncan to fall for it, can Perkins rescue his colleagues and deliver justice for Duncan’s two murder victims?
