Master Sargent Jim Barker retires from the military to pursue a new life. As he leaves the base an old Indian confronts him, claiming to be his Uncle Cecil. He tells Jim that his grandfather, a powerful Shaman and protector of their tribe, has passed on and Jim now inherits these responsibilities. Jim is uncertain about this news but follows Cecil to a cave where he takes the infusion that releases him to meet his spirit-half, a large raven.
Traveling through the past, he sees his ancestors, and his parents, attacked by the evil monster who in present time is disguised as Senator Norton.
