There is tension between WING and FUNG. Ironically, they are arranged to work together on a case. FUNG is tricked by some triads. Luckily, WING arrives in time to save him. LAI returns to work. Everyone notices there is conflict between WING, FUNG and her. All colleagues congratulate HO on his promotion. MING, however, takes his encouragement as sarcasm. Finally, he wakes up from his self-centred behaviour after JOE’s scolding. He approaches WINNIE and HO again. NAN leaves TING because of his bad act, but when she sees him working hard in a pub again, she decides to get back to him. FUNG is suspended because someone complains about him making up a case. NAN understands that LAI suspects TING is behind the setup, but she trusts him. LAI spots TING meeting a key witness against FUNG, so she follows them. WING joins in when he spots them too. FUNG feels guilty when he learns that LAI has triggered her old wound from following TING.
