This Jackie Chan martial arts actioner is a bit different than most of his films (although it does have the requisite spectacular stunts and kung fu fights). In it, he plays a police officer who is a member of a SWAT team but leaves it to join the C.I.D. division. His reason for leaving isn't to get more "action," though; it's to keep a closer eye on his feebly-minded brother Danny (director Hung).
