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.

Dragon Reloaded again focuses on adventures of Lung Wai (Ronald Cheng) and his buddies. The three wacky cops, while enjoying their vacation in a quiet village on an outlying island, accidentally mess up a special operation by the SDU squad, hunting down an important criminal. The village's guardian, a Goddess Statue, also gets stolen. The Police Force decides to place Lung Wai and his buddies as local police of the village, but the trio turns out creating more jokes than anything!
