The people of a jungle village are suffering from a strange illness that is killing off the female population. The natives resort to kidnapping women from other regions -- including Jane (Vanessa Brown), the mate of Tarzan (Lex Barker). Never one to hold a grudge, Tarzan offers to deliver a serum that will wipe out the epidemic. Unfortunately, numerous unforeseen perils await Tarzan during his journey through the foliage. The "slave girl" of the title is played by Denise Darcel, whose role as a nurse is secondary but decorative. An 8 X 10 glossy of the underdressed Darcel, her wrists shackled, clinging desperately to Lex Barker's bare legs, turned out to be one of the biggest-selling "pin-ups" of the 1950s. Not bad for a post-Weissmuller Tarzan flick, Tarzan and the Slave Girl falters only during an extended comic sequence involving Cheta the chimp and a bottle of booze.
