A plane lands in the jungle, and Tarzan saves its pilot, the glamorous Kiki Bluet, from its flaming wreckage. Jack and Roger are enamored by the woman, a beautiful heiress to a cosmetics empire, who says she has come to find new natural ingredients for her skin line. Cheetah and his chimp girlfriend don't trust her. Kiki returns to the scene of the crash to find her vials that were lost in the crash. Jane discovers the vials contain monkey glands. Kiki has no conscience about killing animals for her secret, alleged "fountain of youth" formula. Kiki is so bent on finding her vials, that she leaves the smitten Roger to die after being bitten by a snake. Tarzan saves him, but Kiki then tries to kill Tarzan by throwing him off a cliff. Jane gets involved, showing her that looks aren't everything.
