The bullets fly fast and thick in this rip-roaring shoot em-up starring Constance Bennett, Bruce Cabot and Warren William. When city slicker Harry Farrel (William) learns that the ranchers of Powder River, Wyoming, never filed claim to their spreads, he heads west to kick them out and seize control of their land. Accompanied by gambler Belle Andrews (Bennett), Farrel proceeds with his scheme despite the presence of Wild Bill Hickok (Cabot), who's in town to visit a friend. Unable to buy the valley's water rights, Farrel resorts to frame-ups and murder, acts that force Wild Bill to strap on his guns and show how he got his name.
