Some ancient burial grounds must never be disturbed. When a group of cowboys lays claim to an old and sacred Indian burial ground, an evil spirit is released and possess one of them, willing him to go on a horrific killing spree. Four U.S. Marshals, led by a young native American, are brought together to stop the bloodshed; however, they quickly find that in order to stop the evil spirit, they must pursue him in the sacred ways of the Indians. The trail leads deep into the West where each man must resort to the instincts of an animal to finally destroy the ferocious monster.
