A jungle guide leads a party of explorers in search of the ruins of an ancient African civilisation. They are taken captive by a tribe of moon-worshipping pygmies led by an immortal high priest, who develops a fascination with the rugged adventurer and tries to seduce him in return for his friends' lives. Fantasy adventure, starring Johnny Weissmuller and Jean Byron.

Priestess Oma is forever young in this Jungle Jim knockoff of "She" or the La of Opar stories from "Tarzan". The Jungle Jim-type character is played by Weissmuller using his own name.
