Johnny Wiessmuller swings into action as Tarzan! Caught between two worlds, a man who was orphaned in the African jungle as a baby and raised by apes has grown to rule and to protect the wild beasts, a hero known only as Tarzan. When the sole survivor of a merchant caravan tells Tarzan that his companions were all killed by leopards, Tarzan finds the man's story difficult to believe. Tarzan knows the ways of the jungle cats, and he investigates the killings to disprove the man's account. But Tarzan discovers that an ancient tribal leopard cult has been resurrected when he, Jane and Boy are captured. Now, only Cheetah can save the three from a grisly death as human sacrifices to the cult's high priestess in Tarzan and the Leopard Woman.
