Sheena ventures across the waters of Lake L'Bombo to meet a famous scientist seeking the truth about a jungle expedition in the dark lands ruled by the strange Zargan women, who control devil-creatures. When Sheena is imprisoned by these women, her companions attempt a rescue involving a riverboat, a caged ape, and a daring escape, with Sheena ultimately triumphing over her captors through her jungle prowess and cunning.
