Haruko (Kawakami Yu), who is about to get married, visits her grandmother's house for the first time in 20 years with her older brother Junichi. There they find an old prison cell. When I asked her grandmother, she said that her great-grandmother was incarcerated. And that night, Junichi had a dream. It was a dream in which a woman with the same name as her great-grandmother was raped by men in turn in a prison cell.
