Plot
In just 3 days, three cases of Smiling Murder shock Hong Kong. As he looks into the homicide, the young detective Wang Bu Er (Wen Zhang), the police station's reckless buffoon, makes a shocking statement that this is a serial murder.

He and his buddy Huang Fei Hong (Jet Li) embarks on an investigation full of excitement and unexpected events. Huang may appear to be no less muddle-headed than Wang, but in reality, he is the real master of kung fu, and would, without fail, at the most crucial moments, help Wang get out of sticky situations.

Wang initially believes that budding actress Liu Jin Shui (Cecilia Liu) is the prime suspect, but later, she is found to be innocent. Next, he shifts his focus on her sister Dai Yiyi (Ada Liu), among others. Eventually, Wang decides to pose as Liu's boyfriend to lure out the murderer. The closer he gets to the truth, the greater the danger he is in.
