A gold ring sparks off recollections of a previous life for Major Tim O'Hara, one-time Superintendent of Indian Affairs for South Dakota Territory. It is 1865 and the Native American tribes are being corralled into reservations against their wishes, or deliberately starved into extinction. RoShann, last chief of the Sasquatchoni tribe, leads his people in their desperate struggle to survive. When all seems lost, he reveals a mystical secret that might enable them to travel to a land of plenty. After the tribe's disappearance, nightmare creatures stalk the prairies, and the legend of the Sasquatch man is born.
