CHI begs BING to tell KEN the truth about the whistle, but she refuses. BING’s neighbor steals her son’s medical subsidy. Luckily, CHI helps her to get the money back. She agrees to explain to KEN about the whistle. YUEN falls ill. She is diagnosed of a rare pregnancy disease and the doctor advises her to give up the baby. TUNG attracts the police’s attention with his high profile prostitution business. KEN decides to hold another operation to eliminate it. TUNG causes a big loss to the organization, so KUEN forces him to hand over his business to WING. He sends his subordinate TONG to kill her. Luckily, her husband CHOI saves her, but he is injured badly. She knows that it is TUNG’s plot and wants to take her revenge. KUEN advises her to gather some evidence before taking any action. YUEN notices that CHOI’s injury is not caused by normal traffic accident, so she hands over the case to the Regional Crime Unit.
