An adventurer falls for a woman destined to be the virgin priestess for an African tribe.

Dawn, a young white girl who has been kidnaped in infancy and reared by Mooda, an African woman who operates a canteen in the German cantonment, meets and falls in love with Tom Allen, an English rubber planter who is a prisoner of war. Shep Keyes, who has joined the German troops, covets her but realizes he cannot possess her because she is betrothed to the tribal god, Mulunghu. On the eve of the ceremony, he learns of her love for Tom. Tom, meanwhile, is sent back to England, and when the English take the territory from the Germans, Shep tries to incite the natives, who are experiencing a drought, against Dawn because of her love of a mortal. Tom learns from Mooda that Dawn was stolen from a white trader and finds her seeking refuge in a convent. Shep arouses the natives, but Dawn declares her faith in the white man's God, and a thunderstorm brings relief to the parched land, after which Tom claims her for his bride.
