Five prisoners - Teapot (Sammo Hung), Curly (John Sham), Exhaust Pipe (Richard Ng), Vaseline (Charlie Chin), and Rookie (Stanley Fung) meet in their cell to form a friendship.

Following their release, they team up with Curly's beautiful sister, Shirley (Cherie Chung), and form a company called the Five Stars Cleaning Co.

Police officer CID 07 (Jackie Chan) attempts to recover the briefcase containing the phony money, but the case accidentally ends up in the Five Stars Cleaning Co. van.

They successfully enter the mansion undetected, and while socializing with the other guests, Jack privately meets a Triad boss to discuss a new deal for the counterfeit plates.

Sammo Hung got the idea for the film from an old TV show, in which a group of police officers from different backgrounds worked together, each displaying their own particular skills.

The Seven Little Fortunes was the name of the performance troupe that included Hung, Chan and Yuen, whilst they attended the Peking Opera School, The China Drama Academy, as children.
