In this early Western, notorious bandit the Cisco Kid (Warner Baxter) is so feared that he rarely has to fire his gun to rob a stagecoach. His ravishing girlfriend, Tonia (Dorothy Burgess), often accuses him of being unfaithful, but he assures her that he loves only her, and even composes a song in her name. When Cavalry Sgt. Mickey Dunn (Edmund Lowe) arrives with a mission to capture or kill the Mexican Robin Hood, Cisco matches wits with him and discovers an unexpected betrayal.
