Having quit their old gang and gone straight, Bert Allen and Joe Kemp finally own their own ranch after three years, but Joe robs the Riverton bank of the Green River Dam payroll - using Bert's horse, gun and gloves and leaving behind Bert's hat. Bert escapes across the Mexican border and there falls in love with Betty Burke, while Bill, Al Mooney and Dick pursue the $5000 reward for Bert and the robbery loot held by Joe. Bert offers to surrender to the sheriff if the reward money will be spent on surgery for Betty's blind mother.
