It tells the story of a woman, who, having been murdered by her jealous cousin and mother-in-law, returns as a spirit to take vengeance on her killers.

Shi-mak's mother then returns home apparently unhurt, though she acts oddly, showing fear at the sight of the rosary and licking the children like a cat.

Shi-mak returns home to his mother, but when he notices in a mirror that her reflection is that of a cat's, she reveals her true nature as a spirit and attacks him.

Hye-sook, jealous of the couple and resentful of her position as the family's maid, conspired with Shi-mak's mother, who despised her daughter-in-law for her inability to bear children.

He commented, "Lee's direction has at times an almost expressionistic feel, with exaggerated camera angles and weird set design working well to keep the viewer on edge and to give the film a surreal look...

The murky black and white photography, along with some good suggestive use of shadows, gives the proceedings a nightmarish, gothic air".
