Two years have passed since we last saw Nicky and Alf, which we follow into the third season against the organized hash crime money cycle. PTSD-affected Alf has got a new job in the police's expert group; Task Force Nørrebro, while Nicky has gone from being P's handrail to being in the industry as big smugglers. He also runs a functional laundering machine through a juice bar and dreams of a large house on the Spanish coastline. Alf dreams of his colleague Isa, but life rarely goes as planned. Nicky gets a folder with some information that reveals an unpleasant truth about his son, and Alf must keep secret his relationship with Isa as he is to lead a case of a mysterious find in a basement.

A meaningful job is just what the bank adviser, Anna, hopes to achieve in Kredit Nord, where she works, but when a young colleague overtakes her inside and the family is on the verge of economic collapse, Anna has difficulty accepting her fate. Alf only cares about his work, while it is the women of his life who care about him. He himself suggests pills to work together on everyday life and group D in Task Force Nørrebro. Nicky is highly respected in his professional world, but he is privately tricked into meeting with the ex-girlfriend Lina after 2 years. His family is split and his son pays the price.

Anna working for Nicky, laundering the money from his drug dealing through her job at the bank, and meets with potential lawyers from Dubai. Alf suspects that Nicky is involved in the basement deaths, and is the link to the mysterious Marco. However, Alf's boss wants him to focus on the drug smuggler they have in custody instead. The chief police inspector starts to show an interest in Alf's work in Task Force Nørrebro, which does not go down well with Storm. Nicky meets his son, Milas, for the first time in two years, visiting him at his foster family's home under the supervision of a social worker.

After a violent confrontation at home, Anna asks Nicky for help. She continues to organise Nicky's banking businesses while he tries to re-establish his relationship with Milas. Meanwhile, Nicky meets again with Sahar and is intrigued by her.

Alf starts monitoring Nicky's apartment, but does not find what he was expecting. Frustrated, and struggling with insomnia and PTSD, he makes some quick, and bad, decisions, which will have fatal consequences for innocent people.

Alf and the Nørrebro police try to recover after the shooting. He confronts Nicky, and starts a series of raids against the drug dealers to find evidence against him and Marco. But the Chief Police Inspector has other plans for the investigation. Nicky wants to hand over his business to his partner, Lala, to focus on a normal life with his son, Milas. After an unexpected visit from the auditors, Anna is confronted by her new boss, Nete, but she gets the last word.

When Anna finds out that Nete has plans to co-operate with the police, she tries to put a stop to it. Nicky and Lala get off on the wrong foot when Lala starts taking over both Nicky’s businesses and the access to Marco. At the police station, Alf is confronted by his colleague, Stine, about his substance abuse and the mysterious shift of course in the Nicky and Marco case. Meanwhile, Alf continues to be pressured by the chief police inspector to follow a hidden agenda.

Alf’s decision to go against the chief police inspector’s orders following a murder has severe consequences for the Nørrebro Task Force. Marco’s true identity is revealed and Nicky is now forced to deal with his business arrangement with Lala. Alf is on the trail of Anna, investigating her as a possible connection to Nicky, when her husband suddenly comes to her rescue.

Sahar saves Nicky’s life after Lala’s attack. Alf and Stine hunt the wounded Nicky, but find that he is one step ahead of them. Anna realises that Nicky can no longer help her when her family is sought out by Lala and his criminal partners. Nicky seeks a way out. The chief police inspector interferes with Alf’s investigation.

The season finale has Alf on a vicious hunt for Nicky before he escapes the country. Nicky must say goodbye to what is most precious to him and Anna receives an offer she cannot refuse. Alf and Nicky both realise that there are tragic consequences to their actions.
