Renard Dumont arrives in Africa and begins building a trading post. In the process of building his post he has displaced the rhinos and they have moved into gorilla territory. Tarzan attempts to explain this to Dumont but he cares little for the problems of others. The rhinos refuse to leave or share the territory with the gorillas and Tarzan must find a solution to this dilemma before the gorillas are forced to relocate.
