The Long Hair of Death (1964)

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.
