Hiroko (Hashino), an office worker who is about to get married and works at a trading company in Tokyo, is kidnapped by a yakuza, violently raped by dilettantes, and then imprisoned in a cage. In the same cage was Yoriko (Kato), who was kidnapped, confined and trained like Yuko. Yuko spends her days in hell... Without knowing that Yoriko, who believes she is in the same situation, is also a dilettante.
