Mari has found a mistake in Viggo's investigation and a pedophile suspect has been in Oslo the day Christina disappeared. A fierce hunt starts bringing Viggo closer to the final puzzle. Viggo has the wrong suspect, but he starts to understand that the final solution might be closer than he thought.

Mari is getting brutally beaten in a robbery of a gold smith and needs to take a few days off work with a head injury. With lots of spare time, she learns that Viggos ex-wife might not be as innocent as thought, but she is afraid to reveille her new knowledge to Viggo, who is finally starting to work it out with his colleagues whom he has mistreated for years. But as Viggo solves the robbery, the thoughts of someone close to him being responsible of Christina's disappearance cannot let go and Viggo is yet again the bloodhound he used to be.

Viggo realize that his ex wife's new boyfriend has been in the area when Christina disappeared and starts looking for clues. With one focus on his mind, he can't behave at work and decides to leave the police force. But his suspicions are right and he manage to prove that Haavard, the ex wife's new boyfriend, might be the right suspect and this is even more proven when they find a hair from Christina in his car.

Haavard is taken into custody as the prime suspect of Christina's disappearance. Viggo, who left the force, is not allowed taking part of the investigation, decides to find Christina on his own. Certain that she has drowned; he begins to dive in lakes in the area, a hunt that might kill him being reckless while diving. Meanwhile, Haavard refuses to have anything to do with the disappearance of Christina, bringing Viggo closer and closer to the abyss. Eventually, Viggo breaks in to custody, interrogating Haavard himself, only to learn that Haavard might be innocent

Viggo is saved in the last minute, and while floating between life and death; Viggo dreams that Haavard is dead. Telling Mari about his theory, Mari is getting scared of Viggo as his concern turns out right. Haavard is found dead on the cell, but everybody expect it to be suicide because of the guilt of being Christina's killer. Viggo refuses to let it go, only to be suspected of killing Haavard, while he is getting closer and closer of solving what happened to Christina.
