 In a 15th-century feudal village, a woman is accused of witchcraft and put to death. Her beautiful older daughter knows the real reason for the execution lies in the lord s sexual desire for her mother. After confronting the lord on the matter, she, too, is killed. A much younger daughter is spared and taken in by her mother s killers. Once she is of age, as a horrible, deadly plague sweeps the land, she marries the lord s worthless son. Then, during a brutal thunderstorm, the older daughter mysteriously reappears and begins to avenge her mother s death.
