Amron, an Egyptian general, was placed in a hypnotic trance by his father for 6,000 years until his tomb was discovered by an expedition lead by scientist Dr. Salle. The Red Norton bandits kill most of the expedition and their leader Norton stabs Dr. Salle in the back. However, Norton out of curiosity reads the translation needed to revive Amron. The Egyptian general was instructed by his father's spirit to fight evil, so he rescues an American reporter named Nancy Taylor from the treacherous Norton and takes her to help the wounded Dr. Salle. Afterward, Amron, now known as the Phantom Sphinx, deals out justice to the band of thieves.
