Plot

Tarzan and Jane have left Africa, married and settled in London. Their pre-teen son, Jack, dreams of jungle adventures like his father's, but is discouraged by his parents. He sneaks away to see a trained ape called Ajax (in reality, Akut, an old friend from Tarzan's youth). The ape's trainer is really Ivan Paulovich, an old enemy of Tarzan's, who is looking for a way to enact vengeance. He kidnaps Jack and takes him to Africa.
