Under orders to set out for an operation, HON-TO learns that ON TIN-MING and his three armed henchmen have taken a large amount of civilians hostage at the high court. With HON-TO and his team members arriving on the scene to help evacuate the people there, out of the blue, TIN-MING steps out alone, asking to have a word with HON-TO. TIN-MING not only demands supplies from the police so as to run away, but also requests to meet up with a female police officer called CHUNG WAI-YAN. However, HON-TO uncovers that WAI-YAN used to be an undercover cop years ago and vanished without a trace when the mission completed. Meanwhile, HOK-LAI and the others sweep into the court through other entrances, exchanging gunfire with the criminals, during which one team member, TSE KAR-SING, accidentally falls into TIN-MING's trap and is injured.
