Within a few years, petty crook Chiu rises to gang leader. But his professional ambitions are actually quite different: he wants to leave illegality behind and make a career for himself and his lover in Canada... as a chef. However, this craft must first be learned and Chiu's talent in the field of cooking leaves much to be desired.

A young man wants to be a Hong Kong police officer but is too short to qualify. However, he doesn't let that stop him: he goes around impersonating an officer, investigating crimes and busting criminals. One day, he interrupts a bank robbery (by three men in drag), gets shot in the process and dies. When the case is assigned to a female investigator, he returns as a ghost to lend a hand at solving the robbery.
