Five triad gangs hold equal parts of the East District in a stranglehold, and the police are helpless to rein in the violence. Relations between the gangs are civil until gang leader Jimmy is murdered, leaving aggressive No. 2 man Blackie in charge. Blackie's oath of vengeance pits the gangs against one another in an all-out war that threatens to destroy the district. Shawn Yue, Elanne Kwong and Ada Choi star in this explosive actioner.
