Na Bonggu is a pro when it comes to satisfying women – which makes him the perfect host (a gigolo). After spending the night in a motel with a wealthy client, he is approached by a girl he presumes to be a con artist: Seulbi. It turns out that Seulbi has a connection that can help him pay off his 3 million dollar debt. The two visit Madam Hong, who gives them a mission to seduce five rich women. They will have to complete the missions... Or pay the price.
But the job doesn't come without its dangers: Bonggu and Seulbi are forced to wear electro-shock collars equipped with a tracking device.
