Office lady Ryou Saeki is forced to borrow money from her company's president to pay off her brother's debt. In return, she must assist him with his impotence treatment as interest. With her job and financial stability at stake, she has no choice but to endure the president's rough sexual demands. Meanwhile, Natsumi Kawahama, a secretary working at a health food company, is turned into a sex slave by the chairman of a special corporation—a former Ministry of Health official—to keep the secret that their products contain meat-and-bone meal. Both women are pushed into desperate situations that threaten their very existence.
