Irish McCalla, the statuesque heroine of TV's Sheena Queen of the Jungle, heads the cast of She Demons. Shipwrecked on a volcanic island, spoiled heiress Jerrie Turner (McCalla) and explorers Fred (Tod Griffin) and Sammy (Victor Sen Yung) fall into the clutches of unreconstructed Nazi scientist Osler (Rudolph Anders). Experimenting exclusively on beautiful, busty women, Osler hopes to create a race of super-persons, infusing his subjects with a powerful element known only as Character X. Fred and Sammy race against time to save Jerrie from becoming another of Osler's hideously mutated victims. She Demons is another triumph from director Richard Cunha, whose science-fiction quickies of the 1950s are among the worst films ever made.
