Three police officers driven by different motives decide to join forces to defeat Tien and his gang of thieves. Chan is gunning for Tien after his fiancee Ka-Yee was killed during a violent robbery committed by Tien's gang. Inspector Fong was attacked by Tien during a routine roadblock inspection. Meanwhile officer King-Ho is searching for his missing brother, who went undercover in Tien's gang two years ago. The three cops pool their individual resources and talents to wage war on Tien and his gang, only to discover that the recent series of high profile robberies are being masterminded by another, unknown villain.
