In 1888, in a makeshift cabin at the edge of the West African rainforest, a child is born to Lord and Lady Greystoke, a castaway English diplomat and his young wife. After the doomed couple dies, their infant son is raised by the she-ape Kala, who calls the boy Tarzan--2White-Skin3 in the language of her tribe. As Tarzan reaches adulthood, his strength and agility, quickness of mind, and skill with his father's knife make him the most feared and respected...

The evil Rokoff kidnaps Tarzan's infant son Jack. While trying to save him Tarzan is caught in Rokoff's trap and must use his skills learned from the jungle to save his small family.
