In Hong Kong, an elite gang of robbers - regarded as somewhat of a crime dream team - is formed, each member selected for their previous well-planned, swift, and successful operations. They are fearless and lethal, even going so far as to kill an undercover cop to humiliate the police. However, internal strife is brewing among the team. Three of its members plot to get rid of the leader, dissatisfied that his share of the loot seems disproportionate. The questions remain: will this faction of the gang overcome their leader, and could this gang of strong-minded thieves hold up without him?
