After a police shootout where she killed a man, criminologist Maggie Tall Bear Sloan retires from the force to enjoy peace and quiet in rural California. When sets of young twins are murdered in her town, the local sheriff recruits her to solve the gruesome killings.
But to catch a killer, Maggie either accepts her true nature as a "pukkukwerek" - the shapeshifting monster killer of Yurok legend - or more children will die. As the manhunt intensifies and her own family is threatened, Maggie will do whatever it takes to keep them safe. Whether she's awake or asleep dreaming, Maggie is faced with a difficult choice: embrace her heritage - even if it means turning into myth itself - or deny that heritage and lose everything.
