In China, producing 50 grams of meth is punishable by death. Drug manufacturer Timmy Choi (Louis Koo) has produced TONS. So when given the opportunity to save himself if he helps straitlaced police commander Zhang (Sun Honglei) infiltrate his gang, Choi has no choice but to set in motion a series of events that will result in bloody consequences for criminal and policeman alike. Action master Johnnie To composes his carnage like a true maestro, which makes the spectacular shootout that concludes this film something like his Fifth Symphony.
