Tarzan the Untamed

World War I enflames East Africa as German troops raze the Greystokes' estate, where Tarzan returns to find the charred, lifeless remains of his beloved Jane. Consumed by vengeance, the ape-man wages guerrilla warfare against the hated enemy, using his most savage tactics to help the Allies drive the invaders from his land. As the British army prevails, Tarzan departs to rejoin the great apes that are his family—only to be confronted by a trackless wasteland that stands in his way. Having endured a trial of unimaginable torment, he enters the inaccessible valley of Xuja, the city of maniacs. Outnumbered by crazed foes and their lion and parrot familiars, the ape-man must liberate his friends from a city where madness rules.
