harry-boy (nick cheung) is a cop who's been working undercover, as a triad, for the last eight years. the film begins with him busting his boss, don dark (francis ng) and his subsequent re-introduction into the police force and his new partner, lung (anthony wong). harry now finds himself trailed by internal affairs officers and uneasy with lung's strongarm tactics, which he'd experienced first hand when he was operating on the other side of the law. needless to say lung isn't overly comfortable with harry's company...

on the other side of the coin, cat (rain li), harry's karaoke hostess, former lover and mini b (derek tsang), his former partner in crime, turn their backs on a man who has betrayed their trust. as harry and lung try to deal with the aftermath of don's removal, their paths cross and harry has to cope with the identity crisis he's now experiencing.

well, on the plus side; it looks pretty good, its got a pretty tight pace, nick cheung and derek tsang put in good performances and there's a few very nicely executed scenes. still, it's pretty short, some of the narrative developments don't quite work for me, it has the tendency to slip into the realms of melodrama and over-eggs its pudding when it runs out of steam.

it verges on being pretty good, but it doesn't quite make it.
