Calhoun must fight both outlaws and indians when his stagecoach, carrying a gold shipment, arrives at a relay station.

Apaches attack Jim Walker as he heads for Lordsburg to pick up a herd of mustangs. Bill Gibson, a scout, saves him, and they both head for Apache Wells, discovering a massacred family along the way. As they bury the bodies, Apaches attack again, but then retreat. The Indians fear a Cavalry patrol, which Jim and Bill join but are unable to convince of an Apache uprising. At Apache Wells, Vance Buckner plans with Jess Cooney and Toby Jack Saunders to rob a stagecoach outside the town. When the stage leaves, Jim, Bill, Jess, and Toby Jack are aboard. At the station, Jim fights with Toby Jack when he insults Janice, one of the passengers. Buckner arrives and, with Jess and Toby Jack, disarms the passengers and demands that the money carried on the stage be turned over to him. After revealing that the robbery was the scheme of Taylor, the district manager of the stage line, Toby Jack kills him. Jim and Bill forestall Buckner's plan to kill them by revealing that an Indian they picked up is Antone, an Apache chief, and that his tribe will surely attack. Toby Jack kills Bill, however, but is himself killed by the Apaches as he leaves the station. Jim and Janice escape but are then captured by the Indians; Jim tells them of Antone's imprisonment inside the station and that the Indians must free Buckner and Jess in order to save the chief. The Indians agree, and the outlaws flee. Jim follows them and finds Jess shot, but when he overtakes Buckner, he is unable to kill him in cold blood. The Apaches, who have followed, demand that Buckner be turned over to them so that he may pay for past crimes against Indians, but they allow Jim and Janice to escape to Lordsburg.
