Pop idol Rina Yuki is famous for her amazing stage shows and musical talent, which causes her to be noticed by a new production company, Angel Productions. At one of their concerts, she learns that her father has suffered a medical emergency and has been hospitalized. Kurosaki, the manager of Angel Productions, approaches her to propose that she switch to his company, and after learning that her father owes the company a substantial amount of money and that the company is apparently part of a mafia-related conglomerate, she agrees to work with them.

It turns out that AngelPro also works in the flesh trafficking business, and under the pretense of giving her a "new image," they begin training Rina through public humiliation scenarios and outfits. In between these humiliations, she is ???????? abused on a public subway, taken to a ??? shop posing as a ???? actress, and masturbates in a ???? theater. Once her training is complete, she is auctioned off at a BDSM auction as a ??? slave for 580 million yen (approximately US$5.9 million). Six months later, she returns to her normal life and singing career. The manager and his assistant/slave are backstage, discussing how Rina turned out to be a good buy. Backstage, it is revealed that her father had already died during her training.

At the end of her performance, Rina strips ????? and begins ???????????? with her microphone before losing her mind. The AngelPro representatives leave and Rina's manager collapses to the floor in disbelief. The final shot shows the all-male audience rushing onto the stage and crowding around her as she smiles hollowly, a tear rolling down her cheek.
