In a small Alaskan town, a boy is found with his throat ripped out and the blood drained from his body. The brutality of the murder chillingly echoes a killing from 25 years ago. Out of state detective Barbara Atkins is brought in to assist the sherrif, Jensen Tucker who investigated the original case. However, the inhabitants of Deadheart believe they know who is responsible: one of the nearby vampyr colony who live in an old mining settlement deep in the mountains. Barbara is under pressure to authorize a cull of the entire colony. But the evidence doesn't stack up, people are lying and the more Barbara and Tucker dive into Deadheart's history, the darker the secrets they uncover. As the snow thickens and the nights grow longer, another teenage boy goes missing and bodyparts are found. Time is running out for Barbara and Tucker to find the truth. Are they hunting a cold-blooded murderer or a bloodthirsty monster? And witch is more dangerous?
