Here Sammo plays a criminal ne'erdowell who talks policeman Jackie into helping him smuggle a shipment of arms away from both a corrupt police force and a gang of bad guys. Yuen Biao plays a rival police officer who always seems to butt heads with Jackie, but eventually concedes that they are on the same team.

There are some truly classic action sequences here, primarily Chan-centric ones (which is, of course, to be expected). Of particular note is the bicycle chase/fight, and Chan's death-defying fall from a clock tower (a stunt which nearly cost him his life).

But this really brings me back to my original point. Though Chan's high-flying and boundary-breaking stunts often proved to be the most memorable aspects of his films from this era, they are often more noteworthy for their blatant dangerousness than for their contribution to the film as a whole. And in that context, Sammo, as second-banana, comes to the fore in this film as well as most of his others, with a solid, "meat-and-potatoes" performance that's just plain fun to watch--whether he's defying death, defying a mahjong table, or simply defying a healthy diet.
