Airi Hinata plays Yuka Tachibana, a pure-looking, naturally busty gravure idol renowned for her H-cup figure and alluring physique. She has been supporting her boyfriend Imoka, who is also her agency's president, but their small talent agency now faces imminent bankruptcy. Suddenly, an incredibly lucrative offer for Yuka to star in an adult video arrives. Imoka strongly urges her to accept, but Yuka refuses. Enraged by her defiance and feeling that she has trampled on his love and generosity, Imoka devises a cruel scheme—forcing Yuka to settle the agency's debts with her body by submitting her to a brutal gangbang with clients. The film depicts her kidnapping, complete physical restraint, repeated rape, and intense humiliation as her dignity is stripped away.
