Sayuri is a 42-year-old housewife from Nerima who has been married for twenty-one years. She has a kind husband and a grown daughter, but her marriage has been without sex or even kissing for about fifteen years, leaving her lonely and no longer seen as a woman. With her daughter now away at university, Sayuri longs to feel the thrill and passion of her younger days one last time. She spends a single day with a temporary boyfriend, ending her search for intimacy with a passionate extramarital encounter and a creampie.
