Cantonese pop star Ronald Cheng stars as spoiled rich kid Dragon Lung, who spends his days idly loafing with his fellow teenaged trust-fund brats, Sue-hei (Sam Lee) and Gold (Tat-ming Cheung). When the trio's frustrated fathers force their sons to attend a police academy for some much-needed discipline (or else face the loss of their hefty inheritances), the would-be cadets bungle their way through boot camp in a series of madcap, gun-fueled hijinx.
