Two white explorers, American Tom Dawes and Scotsman Sandy Kemp, travel to the Dyak villages of Borneo, where they hear stories of a primitive, remote tribe, that is ruled by a "white goddess." Intrigued, Tom and Sandy travel upriver to the village and are captured by the hostile tribesmen. Because they have entered a sacred place, the men are sentenced to death, but are saved when they hear a woman's voice say that they are to be made blood brothers of the Dyaks..
