In the final chapter of The Phantom Empire, Gene Autry is saved by Oscar (Smiley Burnette) and Pete (William Moore), who manage to drag him away from Murania's feared disintegrating atom-smashing machine. In the control room, Queen Tika (Dorothy Christy) can only watch as a bumbling Lord Argo (Wheeler Oakman) turns the out-of-control atom-smasher on himself and Murania. Deciding to die with her people in the melting Murania rather than live in the undesirable surface world, Tika allows Gene and his friends to escape the underground kingdom. Back in his own domain, Gene tricks Professor Beetson (J. Frank Gledon) into revealing that he, and not Gene, killed Frankie's (Frankie Darro) and Betsy's Betsy Ross King) father. With Radio Ranch safe from usurpers, Autry and his friends perform "Uncle Noah" to end a rather eventful broadcast season.
