During an armed robbery operation, the Yuen brothers — Dragon (Louis Cheung) and Mo (Andy On) — unknowingly walk into a police trap set by the East Kowloon Regional Crime Unit, led by Emergency Unit commander Ben Cheng (Alex Fong). The mission ends in tragedy when an undercover officer is killed and several officers are severely injured. Ben is demoted following the failed operation, while the surviving criminals escape and swear revenge.
