John Greystoke, Jr. was just a toddler when he accompanied his adventurous mother and father on a journey into Africa in search of a mineral. That trip turns tragic, however, when their helicopter crashes in a storm, leaving young John the sole survivor. Raised from that day forward by a motherly gorilla named Kala, the boy, now named Tarzan, quickly integrates into the family of primates. Nearly a decade later, Tarzan encounters beautiful Jane Porter, and begins to long for human contact. When Jane returns to the jungle accompanied by smooth-talking entrepreneur William Clayton a few years later, her relationship with Tarzan is rekindled. But while Clayton has ostensibly come to the jungle to support Jane's conservationist endeavors, he's actually searching for the very same energy source once sought by Tarzan's father, and hopes to turn a tidy profit by exploiting the precious resource.
