The film begins with real archive news footage from 1979 of a 12-year-old Martin Bryant being interviewed in a burns unit of a hospital after playing with fireworks. He is asked whether he has learned his lesson not to play with them again; he replies that he would play with them again.
Nitram is an intellectually disabled young adult who lives with his parents in Tasmania. He regularly sets off fireworks, which upsets the neighbours, and sells his fireworks to schoolchildren. His father has recently been approved for a business loan with which he hopes to buy a bed and breakfast that Nitram will help run. Nitram begs his mother to buy him a surfboard after seeing an attractive woman with a surfer, but she is exasperated and refuses.
Nitram starts mowing lawns to make money. In the process, he meets a neighbour named Helen, a retired actress and heiress, who offers to pay him to walk her dogs. The two quickly become friends, and Helen buys him a car, despite Nitram not having a driver's licence and exhibiting a dangerous habit of grabbing the steering wheel when the two are driving.
Nitram becomes increasingly frustrated with life at home and tells his parents he is moving in with Helen, who permits him to stay in a spare room but insists that he get rid of his air rifle as it upsets her. On his next birthday, Nitram introduces Helen to his parents; his mother tells Helen an anecdote about a young Nitram taking pleasure in the pain he caused her after pretending to be lost.
Despite having the funds for the bed and breakfast, Nitram's father's offer is rejected when another couple makes a higher offer, and he becomes despondent. Nitram asks Helen if the two can visit Hollywood, Los Angeles, but on the drive to the airport the next day he once again lunges for the steering wheel, resulting in a devastating car crash that kills Helen and severely injures him. When questioned by police, Nitram lies that he was asleep at the time of the crash.
Nitram, having inherited Helen's decaying mansion and over half a million dollars, starts to drink heavily. His mother asks him to help his father, who is severely depressed. Nitram then desperately attempts to buy the bed and breakfast, but the new owners flatly refuse. Several days later, his father's body is found in a nearby river after an apparent suicide. After he shows up to his father's funeral dressed in an electric blue suit and hat, Nitram's mother refuses to let him attend, fearing he will embarrass her. The increasingly isolated Nitram begins to take frequent overseas vacations by himself and practises shooting with his air rifle.
While watching the news one night, Nitram sees a report about the Dunblane massacre. He then becomes obsessed with guns, purchasing an unlicensed Colt AR-15 and shotgun and ordering a handgun. One day, he drives to the bed and breakfast his father wanted to buy and shoots the owners, then drives to the café where Helen and his parents celebrated his birthday. After ordering food, he sets up a video camera, retrieves a rifle from his sports bag and opens fire on the tourists. At her home, Nitram's mother smokes, unaware of the news report of the massacre playing in the background.
On the review aggregator website Rotten Tomatoes, Nitram holds a 93% approval rating based on 121 reviews, with an average rating of 7.9/10. The website's consensus reads, "Nitram asks viewers to face a gut-wrenchingly grim moment in Australian history—but rewards that effort with a gripping, well-acted character study."[17] On Metacritic, the film has a score of 81 out of 100 based on reviews from 26 critics, indicating "universal acclaim".[18]
Reception in Tasmania
The film was met by widespread controversy within Tasmania itself. Kelly Spaulding, mayor of the Tasman Council, which includes Port Arthur, condemned the choice to make the film. The Alannah and Madeline Foundation, which was established by Walter Mikac whose wife and two young daughters were murdered in the Port Arthur massacre, released a statement also condemning the choice to produce the film. The Police Association of Tasmania, the union for Tasmania Police, indicated it was worried how members of the union's mental health would be impacted.[19] The Star Theatre in Launceston and the State Cinema in Hobart were the only cinemas in Tasmania to show the film. However, the State Cinema chose not to advertise the screenings.[20]
The production company invited arts minister Elise Archer to meet, but she declined. Screen Tasmania declined to fund the film. The then-Premier of Tasmania, Peter Gutwein, stated to the House of Assembly that it made him uncomfortable. Other state politicians including Brian Mitchell, federal member for Lyons, and Rebecca White, Leader of the Opposition, expressed concern.[21]
