I am drowning, bound by pleasure, sinking deeper and deeper. Ai is a caregiver who has returned to work after her husband lost his job. However, the elderly man she is put in charge of is a personality disorder that has caused many helpers to be unable to keep up with him. Ai has hot porridge thrown over her body and has urine in a shibin poured over her head. She is even forced to stroke his penis while bathing, and if she doesn't like it, she drowns him headfirst in the bathtub. However, the elderly man has suffered repeated heart attacks and does not have much time left. Ai masturbates naked while being stared at with eyes that reveal his animalistic nature. She is called in the middle of the night and has sex as if she is being violated. Her ordinary daily life is turned upside down. "If I only have one year left to live, even if it only lasts a week, I still want to hold you," "I wanted someone to want me at the risk of my life, I always wanted to be loved seriously."
