Tarzan and Boy are living on the Great Escarpment, though Jane has returned to England to tend to her sick mother. A small force of German paratroopers lands and takes over the lost city of "Palandrya" as an advance base for the conquest of Sub Saharan Africa. Tarzan continually ignores the requests for help from the helpless and enslaved Palandrians, saying, "Jungle people fight to live, civilized people live to fight."
