An expedition team arrives on Tarzan's escarpment. By chance, the two villainous members Medford (Tom Conway) and Vandermeer (Philip Dorn) find out that there is plenty of gold on the escarpment. They kidnap Jane and Boy in order to make Tarzan show them the location of the gold. After Tarzan complies, Medford shoots him and mistakenly presumes he is dead. Soon the group is captured by natives, whereupon Tarzan, comes to their rescue.
