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 a plane crashes deep in the heart of Africa, Tarzan (Gordon Scott) guides a stranded millionaire and his guests through mountains, steaming jungles and lethal swamps. Even with the ever-present danger, two ladies in the band are drawn to the savage virility of the lord of the apes. But no wild animal presents endangers the survivors as much as a big-game hunter and his plot to sell the Europeans into slavery for a fortune in ivory in Tarzan and the Lost Safari.
