Episode 1

S1 E1: The officer in charge of Team A, CHIN HON-TO, leads the rookies of the Special Duties Unit (SDU)/Flying Tigers together with his current team members to conduct some outdoor training. While there, one team member, YU HOK-LAI, demonstrates how to successfully hop on the roof of the high speeding car driven by his co-worker, CHONG CHEUK-YUEN, from another roof of a moving car by solely depending on his own feeling and trust built between his team members. Having seen this, HOK-LAI's girlfriend, SO MAN-KEUNG, who is also one of the rookies, feels very satisfied. Unfortunately, MAN-KEUNG sprains her ankle while jumping...... 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. HON-TO's former subordinate, CHEUNG KAI-KWONG, was transfered to join the CIB after leaving Flying Tigers. He just arrives at that court to give testimony, so he tries to assist the hostages to escape by taking advantage of the chaos there...
