After her father-in-law falls down the stairs and injures himself, Kanna and her husband visit the widower, who has lost his will to live. Once her husband leaves for work, she devotedly tends to his father and gently wipes down the body he has been unable to bathe. Her touch awakens instincts dormant for years. Overwhelmed by a woman’s warmth and Kanna’s resemblance to his late wife, the father-in-law loses control and embraces her. Kanna resists, but his newly rekindled desire will no longer stop.
