In the second half of this dark period drama, office worker Nana reads an erotic novel alone under a heated table, becomes aroused, rubs herself against its leg, and fingers herself to a trembling orgasm. A call from the company president sends her to entertain an important client in exchange for double pay. At the restaurant, the client's president and executive keep pressing drinks on her until she is incapacitated, then bind and sexually assault her. Her body is forced through repeated orgasms with a vibrator and deep-throat abuse despite her mental resistance. As her awareness fades, overwhelming physical sensation takes over and she begins moving her hips on her own, experiencing a disturbing sense of power as the men climax. Something inside her changes as the story closes.
