Plot
Dawn is a white girl who was kidnapped in infancy and is raised by a black native named Mooda, who runs a canteen in a German colonial settlement in Africa. Dawn falls in love with British rubber planter Tom Allen, who is now a prisoner of war. A native black tribal leader is also in love with Dawn and becomes jealous when he hears of Dawn's love for Allen. The Germans force Allen to return to England for attempting to steal Dawn, whom they believe is half black.
When the British regain control of the territory and expel the Germans, Allen returns to the colony. The settlement experiences a drought and the local tribal leader attempts to incite the natives against Dawn, claiming that God is angry because Dawn has dared to love a white man. Allen is unable to save Dawn because the colonial authorities refuse to act unless they have proof that Dawn is entirely white. Mooda confesses that she is not Dawn's true mother and that Dawn's real mother was white, a fact that Dawn's father confirms.
Allen quickly brings British troops just as the natives are about to sacrifice Dawn. During the ceremony, one of the virgin priestesses reveals that the jealous tribal leader has been lying about Dawn and that God is not interested in Dawn as she is pure white. The priestess also reveals that the tribal leader had violated her chastity and claims that the true reason for God's anger was this sacrilegious act. The tribal leader is deposed and sacrificed to the anger of the natives, and the drought quickly ends as rain falls. Dawn and Allen, happily reunited, sail to England together.
