After robbing a small suburban bank, a gang of outlaws led by Bill Kilgore hides out in the neighboring town of Red Rock. Failing to interest Carmen Harroway by his rough romantic attentions, Kilgore forbids the terrorized townspeople to patronize her small confectionery store. A stranger, Bob Vincent, appears in town and, after becoming friendly with Carmen, inexplicably joins Kilgore's gang, passing himself off as a forger. Kilgore and Vincent plan to rob a mail train, but, just before the appointed time, Kilgore kidnaps Carmen, and Vincent, who tries to help her, is knocked out in a fight. Kilgore ties him to a handcar and sends it down the line toward an oncoming train, but Vincent frees himself and stops the train, thus averting the robbery. Kilgore and his gang are captured with the help of Vincent, who turns out to be the president of the robbed bank. He retrieves the stolen bonds and asks Carmen if she would like to become a banker's wife.
