A con man's plan to steal an heiress's heart -- and her fortune -- gets complicated when she falls for the handmaid he hired to help with his scheme.

Gon, a Korean hitman bred in the United States where he works for a Chinese triad, usually flawless in taking out his targets, makes a terrible mistake in fulfilling a mission. Swamped by feelings of regret, Gon no longer wants to be a hitman, but, in order to tie up loose ends, his boss forces him to do another job in Korea.
