In the depths of the Norwegian winter Vilhelm Thygesen discovers a frozen young woman in his garden. She has been stabbed to death. A well-known left-wing lawyer and no friend of the police, Thygesen is now semi-retired and taking life easy. Stribolt and Vaage, the police officers assigned to the case, assume the victim was a drug courier from Eastern Europe and suspect Thygesen is somehow involved. Shortly afterwards a young motorcyclist belonging to a biker gang once represented by Thygesen is killed in an accident. His bike has been tampered with. The police set out to establish the connection between the frozen woman, Thygesen and the bikers who are terrorising the neighbourhood.
