An aristocratic English family is marooned off the coast of West Africa. They find their way into the interior of the dense jungle that lines the coast and here, Lord Greystoke is killed by a predatory ape. Lady Greystoke survives with her infant boy, but in a few months, she too succumbs to the perils of jungle life. The baby is adopted by a maternal she-ape who nurses him along with her own child. This marks the dawn of a legend – Tarzan of the Apes.
