A housewife who has been married for 20 years is suffering from the abnormal sexual desires of her father-in-law, who lives with her while her husband is on a solo assignment. At first, the father-in-law was a quiet, good person, but in reality he has a strong obsession with the female body, and once when he forcibly pinned her down, she was filmed. Using that video as leverage, the father-in-law began to demand her body day and night.
