Na Bonggu's a professional when it comes to pleasing women - which makes him the perfect host (ie. gigolo). After a night spent in a motel with a rich female client, he's approached by someone he presumes is a female con-artist: Seulbi. Turns out Seulbi's got a connection that can help him pay off his 3 million dollar debt. The two of them meet a Madam Hong, who tasks them with seducing five wealthy ladies. But the job isn't without its dangers: Bonggu and Seulbi are forced to wear shock collars outfitted with a tracking device. They must complete their mission... or pay the price.
