FUNG analyses YUEN’s information and realizes that CHOI’s injury is caused by a potential murder case, so he watches through the recorded videos and finds out that the suspect is TUNG’s subordinate TONG and has him arrested. During a sect leaders’ meeting, WING forces TUNG to admit his murder plot, but he denies it. KUEN orders him to hand out his account book to annoy him. KUEN is thankful to CHOI for saving WING’s life. CHI finds out that YUEN is using drugs to control her condition, so she encourages her to tell FUNG about it. The Regional Crime Unit Superintendent PANG announces that KEN is the new superintendent, FUNG’s direct boss. FUNG’s subordinates TING, FA and TAI are annoyed with KEN’s working attitude. KUEN is having a birthday party when KEN’s team arrests him and TUNG for suspected involvement in a traffic accident.
