While playing in the park, Chihiro suddenly feels a strong urge to pee and hurries into the bushes. Seizing the opportunity, a man lurking nearby watches her as she starts urinating, then approaches and begins to tease her. Confused and unable to comprehend his actions, Chihiro can only wait helplessly. A few days later, she encounters the man again and follows him home, only to discover a house filled with men harboring twisted desires. One by one, they begin to bully and dominate her in every way.
