A grotesque corpse is found buried in the Swedish town of Gothenburg. Detective Inspector Markus Hauer investigates the mystery and slowly uncovers an incongruous victim.
Markus Hauer is called upon to solve the mystery that has its beginnings in the mid sixties.
After a work-related personal tragedy he is working directly as a subordinate to the head of the Detectives reconnaissance team. But when it is revealed that Hauer indirectly has caused two deaths, he is re-assigned against his will, to the Cold Case-group. When the daughter of the dead man is trying to seduce him, Hauer is having trouble staying faithful to his wife.
All this while the city is shaken by a sniper who is apparently indiscriminately killing innocent people in the Gothenburg Traffic.
