Unable to endure her husband's infidelity, Misuzu leaves home and takes refuge with a relative's cleaning company, where she begins living and working on-site. However, she becomes the target of harassment by the male cleaners, who gradually take control of her body. While mopping floors, she's forced to work as her buttocks are slapped repeatedly. She suffers involuntary urination, and is made to feel pleasure as the men torment her groin with their rubber gloves. Initially repulsed, Misuzu finds herself powerless against the men's desire for her, slowly succumbing to their advances. Entangled in a mix of pleasure and humiliation, she is led down a new, depraved path.
