 Humiliated by her Aunt Hortense (Grace Goodall), Lettie Morgan (Ann Rutherford) runs away from home. Mixing with a troupe of show girls, led by Otto (Henry Roquemore), she is mistaken for the expected leading lady and heads for California with their wagons. They miss the main wagon train and are attacked just as they cross the California border, but are rescued by Captain Tex Autry (Gene Autry) and his troop. Lettie believes Tex has been insolent for condemning the show troupe being on their own unprotected, and reports him to Colonel Seward (Frank LaRue) at Fort Henry. Horses are stolen from the fort that night by renegades led by Buck LaCrosse (Warner Richmond) and Utah Joe (Alan Sears), and when Tex goes in pursuit, he is believed to be a traitor, captured and condemned to death. Judge Lane (Niles Welch), in on the plot and hankering for Lettie, is asked by Lettie to intercede, but he double-crosses her. Aided by his pals, Frog (Smiley Burnette) and Buffalo (Bob Burns), Tex escapes and takes after the wagon train with which Lettie and the troupe of show girls has gone.
