Three police officers driven by different motives decide to join forces to defeat Tien (Wu Jing) and his gang of thieves. Inspector Chan (Nicholas Tse) heads for Tien because his fiancée Ka-yee (Candy Liu) was killed in a robbery lead by Tien 6 months ago. Inspector Fong (Shawn Yue) was attacked by Tien during a routine roadblock inspection. Policeman King-ho (Jaycee Chan) is looking for his missing brother who is an undercover cop infiltrated to Tien’s gangs 2 years ago. The three join together but finally discover that the robbery was instigated by another unknown man. With King-ho’s courage, Fong’s wits and Chan’s dexterity, the three young men are determined not to let Tien and the instigator escape.
