Quentin Trantino stole the plot of this masterpiece to make his own vision of the story on the acclaimed Reservoir Dogs, in my opinion much worst than this. Ringo Lam is a master on filmmaking, in this film he builds a story of friendship and betray and a new vision of the crime world..Chow yun fat is amazing as always that he works on China, his character an undercover cop who finally become friend with one of the guys that he must betray. Danny Lee's character has blind faith on chow's until the very end when he discovers that the one who was his friend is also his worst enemy. This film is one of my all time favorite, the action, the plot, the acting everything is great. a must seen movie
