In Hong Kong, Nerio Winch, owner of W-Group is murdered on his yacht. The W-Group board of directors meet with Nerio's right-hand Ann Ferguson. They discover Nerio has a secret son named Largo, who was adopted and raised by French-Croatians Josip and Hana along with their own son Goran. Some are skeptical of Largo's existence.
In Brazil, Largo rescues NGO worker Léa from local militia. Léa injects Largo with a sedative and leaves, and Largo is captured by the militia and imprisoned. Nerio's bodyguard Freddy rescues Largo, and they depart for Nerio's funeral. Largo gets drunk and wakes up on a yacht. At W-Group's headquarters he confirms to the board that he is Nerio's son and heir to W-Group.
Senior employee Meyer is shot dead by an assassin whom Largo unsuccessfully chases with the help of Stephan Marcus. Largo is shocked to find Léa with W-Group's competitor Michail Korsky. She flees, but he discovers her real name is Naomi and that she works for him. Korsky announces his intentions to buy W-Group. Ferguson secretly wishes to block Korsky by buying his corporation, but Largo must make the offer. Some skeptical board members are unwilling to lend Largo the money.
Largo travels to his childhood home in Dalmatia, where he meets the now-widowed Hana, and Goran, now a Croatian Army soldier. The next day, Hana finds Largo gone. She is killed by an armed group led by Marcus, who is tracking Largo. Largo has travelled to a monastery where Nerio has a secret safe holding his stocks. Largo unlocks the safe and is cornered by Marcus, who takes his shares and shoots him. Badly injured, Largo escapes to his childhood friend Melina.
Ferguson reveals to Freddy that she organized Nerio's death to lure Largo into bringing the shares so she could buy a controlling stake in Korsky's group. She admits that Naomi is working for her. Freddy requests details of the hostile takeover in exchange for tracking down Largo. Ferguson agrees and sends Marcus for him. Freddy tries to warn Largo.
Largo meets Korsky and explains Ferguson's plans and Naomi's treachery, and that Ferguson intends to announce the new heir to W-Group at a ceremony in Hong Kong. Korsky agrees to withhold his plan to buy W-Group. Naomi reveals to Largo she is a mercenary and Largo agrees to pay her. Largo enters W-Group headquarters in disguise and is shocked to find Goran.
Goran recounts that, while searching for Largo's records, he found his own records, revealing that he was also adopted by Nerio and is also an heir to W-Group. Ferguson had contacted him to be a figurehead for the company in exchange for money, while Ferguson would really hold the power. When Learning that Ferguson had had Hana killed, he agrees to help Largo.
They fight Marcus and Marcus shoots Goran. Largo kills Marcus and grants Goran forgiveness as he dies from his injuries. At the meet, Freddy plays a recording of his meeting with Ferguson. Ferguson bitterly congratulates Largo on his victory. Largo reveals his identity and his plans to take over W-Group to thunderous applause from the audience.
