Kishi is a 37-year-old personnel officer and fairly happy with work, wife and child. But he turns out to be susceptible to a more exciting life. Through his old schoolfriend Daimon he meets the attractive Yoshie and spends a sensational night of love with her. Kishi doesn’t want to leave it at one night. On their second meeting, Daimon is also present and this night turns into a sado-masochistic ritual. A suppressed memory emerges in Kishi: once he raped an elderly woman with Daimon. Kishi again crossed a frontier this night and the relationship with his colleague Yuko also breaks boundaries. He slowly realises that his emotional life is taking a direction that he had never dreamed possible; Kishi moves into a new and dark world.
