Her husband's father falls down the stairs and injures himself. Worried about her father-in-law, who has lost his energy since becoming single, the couple visits her husband's family home. Kanna, the daughter-in-law, sees her husband off to work and diligently helps take care of him. Her father-in-law, who hasn't had a bath yet, is awakened by her gentle hands as she wipes his body. Feeling the warmth of a woman for the first time in a long time, and seeing Kanna somehow reminiscent of his late wife, her father-in-law loses his mind and embraces her. Kanna resists, but her father-in-law, who has regained the flame of life, can no longer be stopped.
