Suzu Otonashi plays a local officer assigned to her first special-investigation mission: infiltrating and exposing an organized groping ring. Wearing a figure-hugging dress and a hidden camera, she begins the sting alone, but the suspects catch her off guard and inject her with a muscle relaxant. Surrounded by their accomplices, she is subjected to a nightmare gang rape. She refuses to submit until her own supervisor betrays her and joins the criminals. Drug-fueled group sex pushes her body and mind beyond their limits; despite her determination to punish them, pleasure conquers her until she displays a shameless orgasm face, convulses into a dazed climax, loses her moral judgment, and descends to their side.
