When triad baddies kill their parents, the oldest brother gets his younger brother and sister out of the house and onto the street. They are eventually taken in by an orphanage, are adopted by different families, and grow up. Now the younger brother, adopted by a wealthy Shanghai family, is getting married to the girlfriend he met during his years abroad at university, and he wants his old siblings to be there with him. And so begins their quest to reunite after all these years, leading eventually to kidnapping and murder, while the older brother (grown up into Julian Cheung) does everything he can to keep his siblings alive, just like he did when they were little. A good action melodrama let down sometimes by going way over the top, a few too many pages taken from the "save my corneas for Jenny" school of scriptwriting.
