Mitsu lives with her husband and father-in-law, but one day, loan sharks suddenly appear. They threaten her husband and father-in-law with documents, forcing Mitsu to take the blame and become their scapegoat. She is subjected to various torments including stripping, cunnilingus, fingering, and vibrator torture. Then begins a nightmarish sequence of 20 consecutive creampie rapes, involving gangbang rape with her husband and father-in-law forced to watch and participate.
