Two perplexed middle-aged losers, Robby (LAM Ka Tung) and Fai (Richie JEN) are good friends. Fai is an honest man. His wife left him with an elderly home business. Fai has tried very hard to keep it running until the owner increases the rent crustily. Taxi driver Robby, who is timid and unreliable, always neglects the conflicts between his mother and his wife. Robby always lives paycheck to paycheck without a financial plan, so he is at a loss what to do. Two robberies involving the money exchange stores across the street encourage Robby and Fai to get a gun and rob the same. It is a destiny to meet the ruthless bandit Mui (Aaron KWOK), who acts wicked, scheming and chivalrous.
