Riders of the Dawn: Jimmy Wakely and Dusty, traveling with the medicine show owned by "Lasses" White, stop at the Ferguson ranch and find the rancher and his wife killed. They take the Ferguson baby to their camp, where outlaws Joe, Slick and Pete attempt to kidnap the baby, while Dusty is reporting the murders to Sheriff Beasley and town mayor Melinda Pringle. Wakely and his singers hide the baby from its legal guardian, Doc Judd Thomas, as they suspect him of being connected with the Ferguson murders.
