Stefan has figured out that his girlfriend Blanka is cheating on him with Christian and he's on the warpath. Hanna is determined to meet her infiltrator, but 'Inez' doesn't show up to the meeting.
Suspecting a leak in the department, Hanna, Bjorn and their boss Tina create a clandestine group to investigate and reduce the risk of their infiltrator 'Inez' being harmed. Christian is threatened.
Hanna, Bjorn and Tina now know there's a mole among their colleagues who reports everything to the Mimica crime family. But who is it? Davor Mimica opens contact with the Mobsters motorcycle gang.
Now that Hanna knows her own son is 'Inez', the police infiltrator within the Mimica crime family, she wants to get him out right away and close the investigation. Christian, however, has other ideas.
