When wolf researcher Emma Salomonsen learns that her father, Marius Stenhammar, has started behaving strangely, she takes her son Leo with her and travels to Østbygda where he lives.
Marius Stenhammar has disappeared. Emma's boss, Jo Ås, orders her to hand over the bloody jacket to the police. But Emma chooses to postpone it until she has spoken to Marius.
The blood on the jacket belongs to Daniel, and the fur is from the alpha male. Kathinka confronts Emma with the evidence, but Emma assures her that it is not a wolf behind the attack.
A fisherman finds remains of Daniel in the river. It seems more and more likely that Daniel was attacked by wolves. At the same time, Emma discovers that Leo has disappeared.
Emma and Leo are on their way back to Oslo when Emma gets one last idea that can help solve the case. A wolf caught on a wildlife camera makes Emma very suspicious.
Emma and Asbjørn Kolomoen are on their way across the border to Sweden. Finally they will know what happened to Daniel. At the same time, Emma receives a text message from Naim.
