Two perplexed middle-aged losers, Robby (starring LAM Ka Tung) and Fai (starring Richie JEN) are good friends. Fai is 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, he always neglected 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.

There are two robberies involving the money exchange stores just across the street encourages Robby and Fai to get a gun and rob the same. It is a destiny to meet the ruthless bandit Mui (starring Aaron KWOK), who acts wicked, scheming and chivalrous.
