Hunters drive animals out of a sanctuary so they can shoot them.

In the African jungle, white hunters Reeves and DeGroot bemoan their meager haul of wild animals and resort to shooting a baby elephant. Before they can claim their prey, however, wild man Tarzan rescues it and concocts a medicinal salve for its wound. After Tarzan prevents Reeves and DeGroot's native porters from taking the elephant, DeGroot talks Reeves into crossing the river into "taboo" Sukululand, where an abundance of wild animals is rumored to exist but where whites are reviled. Reeves soon comes across a huge elephant herd, but moments after felling a bull, he is captured by Sukulu warriors. In the Sukulu village, Reeves is sentenced to die for killing a sacred animal and thrown into a lion-filled pit. Later, in another part of the jungle, DeGroot reports to his boss, Burger, who has been hired by another American, Johnson, to procure a large number of hides, tusks and animal fat. With only ten days in which to fulfill his contract, Burger decides to venture into Sukululand to search for Reeves and hunt game. While driving toward the river, Burger and DeGroot come across Tarzan with the baby elephant and try to claim the animal, but Tarzan once again protects it. After Tarzan reveals that he is taking the elephant to a nearby medical clinic, Burger and DeGroot decide to follow him and persuade the doctor, Celliers, who is the only white man the Sukulus trust, to lead him and DeGroot into Sukululand. At the United Nations-backed clinic, meanwhile, Tarzan delivers the elephant to Celliers and his nurse, Jill Hardy, both of whom are impressed by his jungle salve. Sure that the salve will help a dying patient of his, Celliers asks Tarzan to make some more, and Tarzan heads off to find the ingredients. As Celliers is about to leave for a meeting with the Sukulus' witch doctor, DeGroot and Burger drive up to the clinic. Posing as documentary filmmakers hired by the United Nations, the hunters persuade Jill to talk to Celliers about taking them into Sukululand. Celliers at first refuses, but changes his mind when Jill protests that the film will benefit the clinic. After Celliers, DeGroot and Burger depart, Malenki, one of the hunters' porters, shows up and tries to steal the elephant. Jill stops him and, at gunpoint, demands to know who shot the animal. Malenki reveals that DeGroot and Burger are hunters, and Jill realizes that Celliers is in grave danger. Ignoring the concerns of her helper, Makuma, Jill drives off to find the doctor. Tarzan then returns with the salve and, as soon as he learns about Jill from Makuma, dashes into the jungle after her. Up ahead in the brush, Jill's car engine dies, and she proceeds on foot, thrashing her way through the dense vegetation. After being menaced by a lion and a leopard, Jill falls into some quicksand, but is rescued by Tarzan. In the Sukulu village, meanwhile, Celliers introduces DeGroot and Burger to the chief, who greets them warily. While Celliers talks with the hostile witch doctor, Burger and DeGroot slip away and discover the elephant herd. Burger instructs DeGroot to remove their jeep's muffler in order to scare the animals and cause them to run to the river, where they will be herded across and shot. Just then Tarzan and Jill arrive in the village, and Jane informs Celliers about the hunters' duplicity. After Tarzan races off to stop Burger and DeGroot, the chief orders Jill and Celliers to be executed. In the brush, Tarzan uses his jungle yell to direct the stampeding elephants to turn around, and the hunters soon are trampled to death. Tarzan then rushes back to the village in time to jump in the lion pit with Jill and Celliers and "talk" the hungry animals into retreating. Once the chief learns that the elephants are safe, he forgives Jill and Celliers and thanks Tarzan. His work done, Tarzan hops on a vine and swings away.
