It was an attempt to combine the original Lucky Stars troupe with the similar action comedy ensemble from the Aces Go Places series.
This, combined with the absence of Chan and Yuen, meant that the film contained significantly less kung fu action.
Kidstuff (Sammo Hung) has been asked by police superintendent Walter Tso (Cho Tat-wah) to investigate a case of international ammunition trade between two gangs.
As they embrace each other in a friendly hug, some passing police officers get the wrong idea and decide to tell her husband, Albert (Karl Maka).
Kidstuff goes to ask his old Lucky Stars gang for help (the returning Eric Tsang, Richard Ng and Stanley Fung, and newcomer Michael Miu).
Second is Fat Cat (Kent Cheng), a lazy, corrupt cop, who joins because Kidstuff throws money at him.
