Miho Fukada, the secretary of a finance company's president, is in reality his mistress—a position she was forced into as repayment for her father's debt. The president subjects Miho to daily verbal abuse, barking orders like "Take it off," "Open your legs," "Suck it," and "Beg for it," stripping her of all human dignity. Witnessing this treatment, some employees go beyond mere sympathy and abduct and imprison her. Miho's suffering intensifies beyond imagination, as unspeakable torment is carved deep into both her mind and body.
