An unemployed part-time worker cares for his father at home alone. When caregiver Ema Yano begins visiting three times a week, he continually views her as a sexual target. Before long, he is having sex with her on every visit whenever there is a break in the caregiving routine. She resists fiercely at first, but now accepts him in silence, perhaps because she has given up. This is the record of their year-long physical relationship.
