When JW becomes a drug runner in order to maintain his double life, his fate becomes tied to two other men: Jorge, a fugitive on the run from both the Serbian mafia and the police, and mafia enforcer Mrado, who is on the hunt for Jorge.

JW now lives in exile and is more than ever determined to find out what happened to his missing sister Camilla. Every trace leads him to the world of organized crime in Stockholm. Jorge is about to do his last score – the largest robbery in Swedish history. But during the complicated preparations he meets a woman from his past – Nadja. Martin Hägerström is chosen to go undercover into the Serbian mafia, in order to get its notorious boss Radovan Krajnic behind bars. When an assassination attempt is made on Radovan, his daughter Natalie is pulled into the power struggle within the Serbian mafia.

JW is serving hard time in prison and struggling to get back on an honest path. There are glimmers of hope in his life – some venture capitalists are interested in a new piece of trading software he's developed, and while behind bars he's made peace with an old enemy. This all proves to be an illusion. On leave from prison, and back in contact with his former gang, JW learns that once you've walked in the shoes of a criminal there just may be no going back.
