A police investigator named Arnar travels from Norway to assist in the investigation surrounding Iceland's first serial killer. He works with Kata, the officer in charge of the case, and together they must race against the clock to find the murderer before it's too late. While the victims initially seem unrelated, the trail leads them to an abandoned boys' home named Valhalla, where some horrifying events occurred 35 years earlier.
