Seven weeks after Alice's death, Louise is in mourning and wants to go home as Karina issues her with an ultimatum regarding the case. Alice's death raises a new suspicion which takes the investigation in a new direction. Peter Vinge focuses on his work at a local sawmill, where he receives an unexpected offer from Leif. At the same time, Peter is in conflict with Johannes who remains in a stage of teenage revolt against his father.

Louise Bergstein continues to assist the investigation to find the serial killer, who now has six brutal murders to his name. With Karina Hørup, Louise returns to the first victims in an attempt to find out where they may have met their killer. Peter notices that the police are closer to him than ever before, and at the same time happens to meet Louise again.

Unaware of who he really is, Louise gets far too close to Peter. But the terrible truth lurks beneath the surface. Karina tries to find new evidence for the investigation on her own, and an earlier clue resurfaces, moving the case forward. Peter sorts his life out and gives Johannes a message that his son has a hard time coming to terms with.

The police take Johannes to the station, and Louise fears that the truth about her and Peter Vinge will be revealed. Meanwhile, Peter meets his ex-wife Masja, who has returned from Singapore without notice in order to set things straight. Karina, Søren and Torben desperately try to find Peter before he can claim another victim.
