The Icelandic Police Department is shaken up when a second murder victim is found in Reykjavik. Another body, within a week, killed in the same manner as the first. The police suspect they might be dealing with a serial killer – something Iceland’s never faced before. Police detective Arnar is out of his depth when he is ordered against his will to travel from his adopted home in Stockholm to Reykjavik to help investigate Iceland’s first serial killer case – a gruesome series of murders where elderly people have been stabbed to death. Arriving in Iceland, Arnar is quickly paired up with senior inspector Kata, who protests because she feels she can handle the case herself. Despite the underlying conflict between the two, they must find a way to set their differences aside and work together in order to catch the killer before he strikes again. But the deeper they dig, the clearer it becomes that this horrifying case isn’t just about the present, but about a forgotten crime in the past. As a connection between the victims emerges, linking them to a boy’s home from the past named VALHALLA, the detectives realize that tales of child abuse and a missing boy might play a central role.
