Based on actual Native American folklore of the Mohave, a demon escapes a cluster of stars called, The Seven Sisters and comes to earth on a meteor. The Mohave are in peril of this demon, Kwayu who eats its victims alive and takes their souls. They ask the Seven Sisters for intervention. The Sisters hear the cry of the desert people and build a prison to house Kwayu called Spirit Rock. They teach the shamans of the Mohave how to control the demon with the help of a talisman given to the tribe. But when the last shaman dies and the old ways are forgotten, Kwayu wakes. Can they find the clues to control the demon once again and stop the strange disappearance of the desert people? Or is that knowledge lost forever?
