Viggo had just finished celebrating his promotion with friends and family when he took his daughter Christina to buy ice cream. When he left the shop, the trolley was empty, and Christina has been missing ever since.

A man is found stabbed to death, tied to a tree. Detective Viggo Lust suspects the mans raven-tattoo is important. Still he can't help himself suspecting this case has something to do with the vanishing of his own daughter five years ago.

An old woman is found dead and the victim's daughter has had a hunch something bad has happened. Viggo shows no mercy while ridiculing her and her belief in the super natural and refuses to investigate the case. Viggo is disillusioned and takes a few days off work, letting his partner, Mari Friis, lead the investigation. But Viggo is still being haunted by his dreams and when it is proved the woman was actually murdered, Viggo must face his demons. In a conversation with the victim's daughter he realizes his dreams might lead to finding Christina.

Viggo and Mari start working together on the Christina-case, turning stone by stone once again. Maris positive attitude makes Viggo think in new directions, following new paths. Meanwhile Viggo and Mari find themselves hunting casuals and Viggo is not yet familiar with handling his dreams, which puts him in serious trouble.

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.
