Last of the Dogmen

Montana bounty hunter Lewis Gates finds the corpses of three escaped convicts in the wilderness, apparently shot by primitive arrows. Gates and anthropologist Lillian Sloane follow clues through the mountains to discover a tribe of Cheyenne Indians that has lived in hiding for a century. After twisted Sheriff Deegan uses the violence as grounds for retaliation, Gates must fight to save the Cheyenne from genocide at the hands of a vicious posse.
