The sheriff of Sioux County, Arizona, is notified to locate the bandits' rendezvous. Carl Waters, the sheriff, scouts the country and finally locates them. Returning to the town saloon and dance hall Waters, who is smitten with the fair Caroline Heston, proposes to her. She promises to give her answer the following day. The next morning the sheriff enters the camp of the bandits. Through fear he gives up his oath of office and joins their band. Returning to the dance hall his sweetheart Caroline promises to become his wife if he keeps his oath of office. He hesitates, undecided what to do or to say, and finally leaves the place. Later the bandits visit the saloon. Waters decides that the love of Caroline is worth more than anything else in the world, and telegraphs Broncho Billy, his assistant, to come at once. Broncho Billy arrives. He tells the chief of the bandits, a full blooded Indian, that he would like to join their band. The Indian takes Broncho Billy to a den. Here the Indian pulls a gun on Broncho. Broncho Billy, a cool headed individual, calmly rolls a cigarette and pretends not to notice the Indian. Finished rolling the cigarette, Broncho puts his hand into his inside vest pocket, presumably for a match, but pulls out a revolver and makes the Indian drop his. Broncho Billy then takes him prisoner to jail. The sheriff, Waters, returns to the dance hall, where he tells Miss Heston that he has decided to keep his oath of office. The young couple plan their future happiness.
