Witness Insecurity

Inspector HUI WAI-SUM of the Witness Protection Unit(WPU) and his squad have accomplished the task of protecting a key witness in a drug trafficking trial, which is highly praised by his superior LAU CHAM-KWAN. WAI-SUM goes home to rest, while his fellow colleagues - CHAN KAR-SHI, YEUNG YIU-TUNG, CHEUNG LAI-KUEN and others seize the opportunity for cakes and ale. Later on, WAI-SUM pays a visit to his aunt CHAN YUK-LAN in her fruit store, and she invites him over for dinner. However he is so exhausted that he oversleeps. Upon arrival, he realizes that YUK-LAN and her family have postponed their dinner time just for him. Just then, his cousin, LI HAU-YAN, coaxes him into buying her a tablet computer. Offhand he agrees. Tycoon KIU KONG-HO hangs out with chums for a drink. Out of the blue, a hidden shooter fires upon him, creating a furor among the city……

Quite the opposite, CHI-LAM shows her father a delighted smile upon their returning to her room. For fear CHI-LAM will be disturbed, KONG-SHAN forbids WAI-SUM and his squad from going up to the second floor, which leaves KAR-SHI and YIU-TUNG an unfavorable impression. YIU-TUNG goes to a dinner with WAI-SUM at YUK-LAM’s home, during which he is dazzled by HAU-YAN's trendy style. WAI-SUM bumps into a group of construction workers on his way home, triggering a flashback to his childhood. Although he was rescued from a fire by his neighbor - a construction worker, he lost his parents in that fire. Having found out that KONG-HO is in fact targeted by HUNG FEI, a really powerful man in Shenyang, KONG-SHAN asks a favor from an intermediary – Director CHOU to negotiate with HUNG FEI.

Though smiling, KONG-SHAN utters not a word. HUNG FEI comes to Hong Kong to meet KONG-SHAN, and have a pleasant chat with the KIU brothers. KONG-HO gets stinky drunk so that HUNG FEI offers to give him a lift. However he speaks out of turn infuriating HUNG FEI. All of a sudden, HUNG FEI pulls out a pistol and fires on him. By accident, a foreigner is shot to death by a stray bullet. The whole scene has been caught up by CHI-LAM. HUNG FEI is taken under custody by Patrol Sub Unit (PSU). KONG SHAN dashes for the hospital to visit his brother knowing that a disaster is imminent, as it turns out that the victim is actually a retired judge. HUNG FEI's driver pleads guilty, which differs from CHI-LAM's testimony……
