Expect the Unexpected | ทุบนรก 6 เดือด

A group of inept Mainland criminals botch a jewelry store robbery. The cops, led by the straight-laced Ken and the wise-cracking Sam, begin to investigate the case and quickly confuse the jewel thieves with a group of hard-ass Mainland robbers staying in the same area. In this "cops and robbers" film, a raid on a jewelry store staged by a band of amateur hold-up artists goes horribly wrong, leading to a shoot-out. The elite Organized Crime Bureau team, headed by Captain Ching King Gen, is poised to go into action at a moment's notice. Working as a unit, they bring law and order to Hong Kong streets, where they must rely on their courage and skills to survive.
