A troublemaker sneaks into a luxury hotel in Tokyo and targets a beautiful, big-breasted cleaning woman. While she is working, he suddenly attacks her, violently groping her back, thighs, and large breasts before forcibly restraining her. He binds her wrists, blindfolds her, inserts a vibrator into her anus, and abandons her outside the room. With her breasts exposed, she desperately tries to escape, but in the darkness, she begins to feel uncomfortable vibrations. The sound of a couple walking down the hallway seems almost pleasurable, deepening her confusion. In this vulnerable, disoriented state, she is raped right in the hallway, then abandoned once again.
