A renowned archeologist has uncovered the three thousand year old tomb of an ancient sorcerer who practiced black magic. Clark is covering the story with Los and Lois explores the entrance to the crypt. Inside, Lois accidentally releases the mummy from its sarcophagus and the mummy closes on it. Hearing Lois scream for help, Clark sees a mummy chasing after Lois and feigns an injury to slip away and change into Superman.
The professor shoots at the mummy and the distraction allows Superman to fly Lois away from the mummy. The mummy returns to the tomb and its sarcophagus and Superman goes into the tomb only to find the mummy gone.
Near the Great Pyramid of Giza, a whirlwind near the base changes into the mummy and the mummy gestures at the pyramid. The pyramid flips upside down and starts spinning as the mummy chants.
In a nearby village, Clark and Lois stroll through a bazaar when they see the spinning pyramid moving rapidly in their direction. The two move in opposite directions to avoid the pyramid with Clark changing into Superman.
Superman lifts the pyramid up in his palm and returns it to its original site. Suddenly, Superman is caught up in a whirlwind and is unceremoniously dumped out.
Back at the tomb, Superman rescues the professor from the tomb as the mummy causes it to collapse and the sands quickly bury the tomb deep beneath the ground.
Lois and Clark go to fly back to Metropolis with Lois giving Clark a toy mummy as a souvenir of the trip.
