Two half brothers look so similar as infants that no one can tell them apart. One, the legitimate son of a rich man, is destined for a life of comfort, while the other is condemned to be a slave as he is part black. The mother of the would be slave is also the nurse of the other, to give her son the best life possible she switches the two. Soon the boy who is given every advantage becomes spoiled and cruel. He takes sadistic pleasure in tormenting his half brother. As they grow older, the townspeople no longer notice that the boys look similar, and they readily accept that each is born to his station.
