The Manitou | 1978
When Karen is admitted to a San Francisco hospital because she has a tumor growing on her neck, the doctors come to believe that there is a fetus inside it. The growth is in fact an old, Indian shaman who is reincarnating himself through Karen, and when he begins to see himself under attack from the x-rays being used to examine him and stunt his growth, gruesome things start happening. The shaman is also out to avenge North American's indigenous people who were killed off by the invading white men. Once the identity of the Manitou is understood, another native American shaman is called in to control him, but is no match for his power.
