Although the Thunder Riders sever his rope, Gene Autry manages to grab hold of a tree limb, climb to safety and return to Radio Ranch in time to join Oscar (Smiley Burnette) and Pete (William Moore) for a hearty rendition of Burnette's "I'm Oscar; I'm Pete". The Ranch performers then reenact a stage robbery for the listening audience but nasty Professor Beetson (J. Frank Glendon) has tampered with Gene's rifle and the crooner's partner, Baxter, is killed. Accused by Beetson of murder, Gene manages to escape but is followed from the air by the sheriff. Queen Tika of Murania (Dorothy Christy) watches everything on her surface television and orders the Thunder Riders to capture Autry and shoot down the plane carrying the sheriff and stowaways Frankie (Frankie Darro) and Betsy (Betsy Ross King).
