Tarzan spurns the love of La, Queen of Opar. When he isn't trying to keep the Bolshevik Rokoff and Clayton (pretender to the Greystoke estate) from reaching Opar, he is attacked simultaneously by two lions, dropped into a pit when a volcano splits the ground, nearly sacrificed by sun worshipers, and so on.
