When a severed head is found on a stake in the quiet town of Larvik, Police Inspector William Wisting is called in to investigate. As the media closes in on the biggest story of the year, Wisting's journalist daughter Line receives a tip. Soon, it becomes clear that there is more to this case than anyone thought. A criminal network has lodged itself deep into the roots of the city, and it's up to Wisting to take down the elusive and dangerous Night Man. But hunting down The Night Man will take everything Wisting has, and it's all too easy for the hunter to become the prey.
