Roaming cowboy Bart Andrews is arrested for vagrancy by a sheriff who needs men for the state road gang. On the way to jail, the sheriff stops off at a rodeo, allowing Bart the chance to ride a wild bronc. Bart tames the horse, and, at the urging of some cowboys, the sheriff allows Bart to go to work on the Lawrence ranch. Bart falls in love with Jean Dawson, the ranch manager's daughter, and prevents the theft of a trainload of cattle. Later, Bart surprises the foreman in the act of robbing the safe at the express office; the men fight, the station agent is killed, and Bart is accused of the crime. He frees himself, brings the foreman to justice, and reveals himself to be the real owner of the Lawrence ranch.
