Eri, a newly graduated office lady working at an advertising agency, has just moved to Tokyo. After an accident at work, she is summoned to a hotel by some men during her lunch break. Eri is firm in her negotiating stance, but she accepts a "settlement" agreement to avoid being found out by her company. Using the footage she filmed as a pretext, she is asked to have more sex, and one after the other, she becomes the men's sex slave and becomes addicted to pleasure.
