In the depths of the Norwegian winter, left-wing lawyer Vilhelm Thygesen discovers a frozen young woman in his garden. She has been stabbed to death. Stribolt and Vaage, the police officers assigned to the case, assume the victim was a drug courier from Eastern Europe. Shortly afterwards, a young motorcyclist belonging to a biker gang once represented by Thygesen is killed in a motorcycle 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.
