When a game warden is shot by an ivory poacher looking to make a fortune off the seasonal elephant migration, the poacher falls off a cliff after tangling with Tarzan, but the accidental death causes the man's son to vow revenge.

Tarzan tries to stop a blood thirsty Colonel from taking over an African village with his soldiers of fortune. Tarzan has been rendered deaf by an exploding hand grenade, effectively limiting one of his keen senses. Tarzan relies on his telepathic powers to a lion.

Though still deafened by grenades, Tarzan relies on his animal friends to help him elude the colonel's heavily-armed soldiers.

Tarzan leads a group on the hunt for missing artist Rona Swann, unaware that one of them is merely using the search to cover up gun smuggling.
