Cheung Tit-hong has recorded numerous meritorious deeds, but he is by nature uncontrollable and antagonistic to his bureaucratic superiors. Before reporting his work to his superiors, he has already successfully arrested the gangsters who steal motorbikes. He also saved an innocent teacher from being wrongly accused of theft by recognizing a female pickpocket. Finally, he has subdued fierce armed robbers in the gambling casino by flexibly utilizing a car thief, Boy. The contradictions in working style between Cheung and his superiors naturally lead to numerous scenes of strong conflicts. Because of their common antipathy to the bureaucratic superiors, Cheung and Boy develop close relationship and even genuine friendship as a result of their cooperation in life-or-death struggles.
