Shipwrecked in a dangerous, lion-infested part of Africa, Professor Porter, and his daughter, Jane, find themselves trapped in the heart of the jungle. After evading capture by duplicitous Clayton and his wicked ally, Rokoff, Tarzan rescues Jane from Arab slave-traders, unbeknownst to him that Queen La, the temptress priestess of the hidden city of Opar, and her minions are watching their every move. Now, as Tarzan saves, once more, beautiful Jane from certain death by the hands of the evil ruler, Clayton and Rokoff set their sights on abducting Jane, whose intricate tattoo on her back can lead them to Opar's immense riches. Can heroic Tarzan save his beloved mate, and teach the criminals a lesson?
