World War II is over and the victors govern the country. During the German occupation Storm Steinset was a double agent for the Norwegian Resistance Movement, and his mission is still covert; he gave an oath never to reveal his true activities during the war, even in peacetime.

This means he must live with the fact that his colleagues in the Oslo Police Department think he was a Nazi.

When several policemen who worked for the Nazis during the war were found dead of the same torture methods they themselves used during the war, Storm realises that he too must be on the killer’s death list. At the same time he has been assigned to investigate the case.

Storm’s partner is the police force’s youngest deputy, a rising star Robert Rødberg who dreams of becoming a hero – and despises people like Storm.

In their hunt for the killer Storm and Robert delve into the secrets of the innermost circles of power in the formerly occupied country. There is the threat of a new war breaking out, a war in which secrets from the past war can get you killed.
