When Miss Arizona Williams arrives to take control of the huge ranch she's inherited, she finds trouble in the form of a jealous foreman Rick Jason waiting for her. Jason meets the girl in town and needles her to fury, which earns him the losing end of a fast fit-fight with Cisco. Infuriated, Jason and his henchmen plan to rustle Arizona's cattle, but Cisco and Pancho learn of his plans and gallop off to stop Jason's stampede of thousands of steers with no help!
