Sent to prison with his friend Willie Martin (Ben Cooper), for riding with Quantrill (Fred Graham), the two go along with a jailbreak plan masterminded by former U.S. Army Captain Andrews (Buster Crabbe), who now heads the Arizona Rangers, to grant the men a full pardon if they help the Rangers stop a band of raiders who once rode with Quantrill. Clint has an old score to settle with Montana Smith (George Keymas), one of the Raiders, but plans to take off on his own until both his younger brother and his pal Willie are killed by the raiders.
