A guy with a talent for cards makes his way into the dangerous world of underground gambling in this crime thriller from South Korea. Go-ni (Jo Seung-woo) is a small-town guy with a big appetite for gambling. Convinced he's on a hot streak one evening during a card game, Go-ni bets his life savings on a hand of hwatu, only to lose to a crooked cardsharp. Determined to get revenge, Go-ni sets out to find the guy who cheated him and win back his money. Go-ni's travels lead him to Pyeong Gyeong-jang (Baek Yun-shik), an unusually gifted card player who has gotten out of the game. Pyeong sees a talented protégé in Go-ni and takes him under his wing, introducing him to Madam Jeong (Kim Hye-su), an equally gifted female gambler. Jeong is attracted to the young and handsome Go-ni and takes him on as both a student and a lover, but the young man soon learns how dangerous a gambler's trade can be when he wins a hefty bankroll from Kwak Cheol-yeong (Kim Eung-su), an underworld kingpin who doesn't take losing lightly. Go-ni also foolishly breaks off his affair with Jeong when he falls for Hwa-ran (Lee Su-gyeong), a beautiful woman who runs a nightspot, and makes an enemy of A-gui (Kim Yun-seok), a thug with a hair-trigger temper who holds a grudge against Pyeong. As the various characters come together for a major hwatu tournament, Go-ni struggles to keep his mind on the game as he's forced to keep his eye peeled for enemies prepared to claim his life.
