Kita, a 50-year-old divorcee, indulges in the pleasure of ravaging the dimly lit garbage disposal area of an apartment building. Ignoring the sorting rules, his hands that tear open the garbage bags laugh coldly. The manager, Mrs. Nitori, frowns at his abnormal behavior and her irritation grows. She warns him to "get out," but Kita's eyes are like a snake that has caught its prey. Her anger is powerless. Kita, with a fake "contract" in his hand, manipulates the threads of rape. Nitori's heart is gradually entangled, and her resistance dissipates. Kita's psychopathic smile echoes in the darkness of the apartment. No one can stop him. This game is in his palm.
