Synopsis by Hans J. Wollstein
Despite the deadly radium beam, Frankie Baxter (Frankie Darro) manages to pull the lever that opens the surface entrance to Murania, allowing Gene Autry and sidekicks Oscar (Smiley Burnette) and Pete (William Moore) entry to the underground empire. Queen Tika (Dorothy Christy) finally learns of Count Argo's treachery from Gene but the warning comes too late: Argo (Wheeler Oakman) is about to assume control over the entire palace and most of the empire. Knocked unconscious in the ensuing mayhem, Gene lands on a moving conveyor belt and is in grave danger of being incinerated by one of the Muranian worker robots.
