An expedition team arrives on Tarzan's escarpment. By chance, the two villainous members Medford and Vandermeer 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. Soon the group is captured by natives, whereupon Tarzan comes to their rescue.
It is the fifth in the MGM Tarzan series to star Johnny Weissmuller and Maureen O'Sullivan.
