First he recruits Top Dog (Alan Tam), so called because of his affinity with (and ability to speak to) dogs. Second is Fat Cat (Kent Cheng), a lazy, corrupt cop, who joins because Kidstuff throws money at him. Next is Lambo (Andy Lau) a martial arts expert and lady's man, followed by Long Legs (Anthony Chan) and Libbogen (Billy Lau), a pair of timid beat cops who flee in the face of danger. To complete the unlikely group, Yum Yum (Maria Tung) is assigned to teach the gang her skills of self-defence and disguise. However, the gang ends up not learning anything in their three-day training as they were busy with their numerous attempts to grope her.
