Ayako (Aki Sakisaki), whose husband is a salaryman and also runs a beauty salon, finds herself in a predicament when her sister Kanako takes out a loan using the salon's rights as collateral and then disappears. A debt collector forces Ayako to either repay the debt or give up the salon. She ends up working under Shirakawa, a new manager sent by the debt collector, and is subjected to indecent training. Bound by a vow made through deceit, she experiences shame, humiliation, and the crushing of her pride, yet has no choice but to obey.
