Duffy Burns returns from college in the East and discovers that his father's cattle are being systematically stolen by a band of unknown outlaws. Duffy resolves to catch the culprits, conceals his identity, and goes to work on his father's ranch. There he meets Gloria Carpenter, daughter of one of the outlaws, and falls in love with her. Gloria returns the affection, but she is puzzled by Duffy's constant attentions to the Widow Dodd. Duffy and a sheriff's posse round up the bandits, Gloria's father reforms, and Duffy wins Gloria's love when he explains that his friendship with the widow has been strictly in the interest of capturing the cattle rustlers.
