If you're wondering why this apparent sequel was made before Woo's Hard Boiled, it's because both films are factually unrelated to each other. "Smart" marketing linked this to Woo's successful heroic bloodshed classic only to increase sales. Of course, Jing Wong's film is little more than an attempt to cash in on the success of A Better Tomorrow and The Killer.
The Red Army is on a mission to kill the Daka Lama. He predicts his own ill fate, later that evening he gets seriously wounded. The Red Army fails to kill him, but he's lost a lot of blood and because he has a rare blood type, a race against the clock starts to find an appropriate donor.
With people like Andy Lau, Alan Tam and Eric Tsang on board, this film may sound promising, but in reality it's a pretty cheap knock-off. The first half is boring, the second half pretty action-filled, but the action scenes feel bland and uninspired. If you want heroic bloodshed, there are much better options out there before you should even consider watching this one.
