Two different men are possessed by spirits of Native Americans after they separately wander into a sacred burial ground. When John and Sybil come home with their son after a trip to the Mojave Desert, they bring an unusual stone back as a memento of the trip. The stone seems to cause strange noises and other horrible inexplicable phenomena.
