A lewd indoctrination game takes place in a locked room. Jun, an intelligent secretary who is constantly ignored and mocked at her workplace, falls victim to a group of cunning and deceitful men who obtain scandalous evidence against her. To protect her reputation and prevent exposure at work, she is reluctantly forced to comply with their demands. In a city hotel room, she has repeatedly offered her body after being mercilessly tormented. No matter how much she sacrifices her body, she refuses to let her mind break—this belief being the only way to preserve her self-respect. Though the hateful memories of these men never fade, overwhelming pleasure keeps surging against her will, and she struggles to resist. As the men mock her writhing form, they slowly erode her emotions. The more she clings to her pride, the more her bravado reveals her underlying masochistic desires. Insulted and mercilessly teased, she ultimately succumbs, surrendering to faint ecstasy.
