The husband, Tomoyuki, his younger brother, Masayuki, and his wife, Yumi, who has been working in clinical practice, run a small hospital together. Masayuki is a nurse who is usually unreliable, and Yumi is a noble female doctor who supports the hospital. Their relationship begins to become distorted after an incident. By day, they are the one who gives orders and the one who receives orders, and by night, they are the one who ties things up and the one who is tied up. Yumi, who has become aware of her hidden masochism, gradually develops a perverse desire, and she forgets her guilt towards her husband and becomes obsessed with bondage.
