Dublado e Legendado no OverFlix. Yasuko, a housewife, lives in an urban high-rise apartment with her husband Satoru and her son Takuto. Annoyed by spam calls and door-to-door salesmen, Yasuko slams the door on a salesman’s hand when he tries to squeeze a flyer through the apartment's chained front door. He leaves, but the next day, her nightmare starts.
