Every two years the senior members of the Wo Shing Triad, the oldest gang in Hong Kong, elect an up-and-coming younger boss as their chairman. The two candidates they are voting on couldn't be farther apart in personality; Lok (Simon Yam) is a levelheaded businessman and Big D (Tony Leung Ka-Fai) is a loud, obnoxious, violent criminal. When the voting does not go how some people would have liked, lines are divided and a gang war begins to form.
