Faced with the murder of three medicine men, Navajo police must find the culprit. That the murders appear to be the work of a Skinwalker, or bad medicine man, complicate and illuminate the detective's work.

Young Native American man Thomas is a nerd in his reservation, wearing oversize glasses and telling everyone stories no-one wants to hear. His parents died in a fire in 1976, and Thomas was saved by Arnold. Arnold soon left his family, and Victor hasn't seen his father for 10 years. When Victor hears Arnold has died, Thomas offers him funding for the trip to get Arnold's remains.
