After coming to a resting point, the expedition party is bewildered by an ape call they hear in the distance that is distinctly human-like. Jane also loses her footing, but she is pulled back by a rope. When the expedition party finally arrives at the wall of the Mutia Escarpment, they are forced to scale its narrow precipice, which proves too narrow for one of the men, who falls to his death. James's account of the legend soon proves true when a native, crazy with fear after having seen the burial ground, runs into their camp to take refuge from the brutal Ubangi tribe and then mysteriously dies. Before they leave, James tells his daughter about the legend surrounding the burial site, and warns her that the natives consider the place sacred and taboo and that all who so much as look at it are put to death by tribal witchmen. Though James is reluctant to let his daughter accompany them, he eventually allows her to go when a smitten Harry sides with her. After a tearful reunion with her father, Jane, who says she is 'through with civilization' and prefers to be a savage, insists on joining the expedition on its dangerous trek in search of an ivory deposit worth eleven million dollars.
English trader James Parker and his partner, Harry Holt, are about to embark on a journey beyond the Mutia Escarpment, where a fabled ivory-rich elephants' graveyard lies, when James's daughter Jane arrives from England.
