Convict Karl Varner escapes from prison through a mine shaft. Underground gases transform him into a being of brute strength called the Heap. Prince Ra-Man confronts the Heap, but finds that his powers are evenly matched. Using the lamp of Imhotep, Ra-Man is able to return to the dimension of Ra where he obtains a magical dust. When he returns to Earth he uses the dust to revert the Heap back to Karl Varner, who is then easily captured.
