A tribe that is dying of a mysterious disease kidnaps Jane (Vanessa Brown) and nurse (Denise Darcel) to be slaves to repopulate the tribe. Tarzan (Lex Barker), the doctor and local tribesmen set out to resuce the women and cure the disease whilst fighting off another tribe dressed as trees and using blowpipes. This is a typical Tarzan film though with more than the usual geographical inaccuracies.
