Sinopsis

A woman is seduced by and cast aside by a fickle lover. When the lover marries another woman who starts hallucinating during their wedding, she is accused of being a witch and thrown to her death over a cliff. A strange man rescues her, nurses her back to health, and is told that she must master black magic in order to exact vengeance on her tormentors. She casts a variety of spells over the populace--with the male population as her favorite target, and becomes the queen of black magic. But who, exactly, is the man, and does he have other plans?
