Model Eri was suddenly informed one day that she was to appear in a "Public Orgasm Show." Though she had no recollection of agreeing, the terms were buried within a contract she had previously signed. Subjected to the intense gaze of a large audience, humiliating acts progressively push her body into increasingly severe conditions. Her naked body is projected onto a screen, she involuntarily urinates from embarrassment, audience members participate by tormenting her with vibrators and electric massagers, and a drill vibrator is used on her while semen is injected into her vagina. Through relentless orgasms and pain, Eri's body is gradually trained and broken down.
