Joo-hee, a girl working at a famous officetel, earns money by selling her body. She used to be the ace of the officetel, but suddenly she stopped receiving booking calls. Meanwhile, her friend Ji-young is so busy with bookings that she needs two more colleagues to keep up. Joo-hee is jealous of Ji-young and accidentally hears from a regular customer that Ji-young is providing unconventional services to customers. Angry that Ji-young is stealing her customers, Joo-hee decides to compete with Ji-young for services. Customers are extremely satisfied with the competition, but both Joo-hee and Ji-young feel exhausted and eventually agree to provide the same service.
However, when the bookings gradually dry up, they receive shocking news: Young-joo, who used to work with them at the officetel, has moved to another officetel and is booming with her unconventional services. After some thought, Joo-hee and Ji-young decide to join forces to win back customers from Young-joo. They create a bold and exciting 2:1 service, which keeps the booking phone ringing.
