The fourth entry in the literary porn drama series is set in the Heisei era and follows five mature women, including widows, a mother, a civil-rights lawyer, and an affluent older woman, who are attacked by a home-invasion gang and dragged into a nightmare of sexual violence. Sayo divorced her criminal husband 23 years earlier and gave up her newborn son after the father received a death sentence. Ginji, the detective who raised the boy, later dies fighting the gang. Now widowed after a second marriage, Sayo returns with a female lawyer to meet her son and his foster mother Reiko. The reunion collapses when he learns who his father was, just as a slave-trafficking gang attacks and subjects Sayo, Reiko, and the lawyer to gang rape. The tragedy unfolds across three stories in this 180-minute drama.
