Tarzan and the Jungle Boy

A reporter comes to the jungle looking for a boy who was lost a few years ago. She goes to Tarzan for help. They go to the chief of the tribe where he was seen and they tell them that there is such a boy on their land. At the same time the chief's two sons, Buhara and Nagambi are battling each other to see who will the next chief. Nagambi cheats which Tarzan notices and saves Buhara. Because of his treachery the chief declares Buhara the new chief. But then they discover that only Nagambi knows where the boy is, and because Tarzan foiled him, he intends to find the boy and kill him. Buhara tells them that he will try to find him but their custom doesn't allow strangers on their land and anyone who violates that will be killed, and he warns Tarzan that he will kill even him if he enters their land. Tarzan decides to go and find the boy anyway and tells the reporter that he has to do it alone but she decides to follow him after he leaves.
