Sachiko (Tachibana Mary) is trapped in a cold marriage and takes a job at an upscale club to help support the household. She begins an affair with the club's chief and gives herself to the sexual pleasures her husband never provides. With her lust fully awakened, she loses herself in the affair. One day, while being brought to climax, she catches her husband's scent nearby and deliberately cums as if putting on a show for him—but what follows remains uncertain.
