 There has been a series of mysterious homicides on a Sioux Indian reservation in the Badlands of South Dakota. The investigation of homicides on Native American territory is within Federal jurisdiction, but the FBI is finding it difficult to gather information from the native Sioux. Ray Levoi, a promising but inexperienced field agent who happens to be one-quarter Sioux, is called in to assist in the investigation. As he probes deeper into the events on the reservation, he is torn between his duty to the FBI and his awakening sense of duty to the Sioux nation.
