After years as a homemaker, Mao wants to work again and finds an ad offering ¥3,000 an hour. The only listed requirements are that applicants be women and wear skirts with pantyhose. Her husband calls the offer an obvious scam and mocks her for being naive, so she attends the interview to prove him wrong and is hired immediately on a trial basis. The office tasks seem easy at first, but one day she discovers a hidden camera filming her in the changing room—the first sign that the job was designed to trap and sexually exploit her.
