Now that he was the rich Lord Greystoke, Tarzan became the target of greedy and evil men. His son was kidnapped, his wife had been abducted, and Tarzan was stranded on a desert island where he seemed helpless. But with the help of Sheeta, the vicious panther, and the great ape Akut, Tarzan began his escape. Together with the giant Mugambi, they reached the mainland and took up the trail of the kidnappers. Tarzan sought his wife and his child - and he sought such vengeance as only a human beast of the jungle could devise. But the men Tarzan sought had fled deep into the interior - and the trail was old and well-hidden.
