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.

Jungle Jim fights enemy agents who are trying to steal cobalt while disguised as crocodiles.

A group of skeptical government officials headed by General Randolph are brought to a remote laboratory for a demonstration in "Psychic Materialization", a successful side effect of an experimental drug. But the project scientists had warned that not enough testing had been completed to access safety concerns. In a freak accident during the demonstration to the politicians, a vicious creature is created! Unable to contain the monster, it unleashes unbelievable havoc & destruction against mankind! Reproducing itself at an alarming rate, and all known weapons seemingly powerless against the creature, the scientists are gravely concerned for the survival of mankind!

Jungle-Jim type Johnny Weissmuller helps Professor Blakely look for a missing colleague who is now playing "god" for a bunch of natives.
