In the vast expanses of the Wild West, people kill to survive, so a marksman is highly valued. But if he doesn't want to get into dirty business like King Mabry, he's doomed to wander alone among the snowy plains. By chance he learns that Tom Healy's famous troupe will have to cross the dangerous Wind River Valley. Their guide, cowboy Barker, immediately aroused Mabry's suspicions. And they were justified. Only he, the real devil with a revolver, King Mabry, can save three women from robbery and violence.
