Armed Reaction: Episode 1

Police Special Task Force Senior Inspector SANG and Traffic Police Officer CHI co-habit happily. Regional Crime Unit Inspector FUNG receives some tips about a triad organization ‘Hung Ying’ recruiting some prostitutes from the Mainland. FUNG and his colleagues set up an operation to try to catch the black-hands behind the organization, but the suspects escape. Luckily, CHI helps them to arrest them all. SANG accidentally sends RITA an animated email to propose instead of CHI. She announces the news to the whole police station. SANG loses CHI’s silver whistle during an operation. She is cross and moves out. FUNG’s wife YUEN is CHI’s boss and best friend. She tries to persuade her to get back to SANG, but fails. SANG learns that a prostitute BING has found CHI’s whistle, so he looks for her. A sect leader of Hung Ying TUNG sees BING holding the whistle and scolds her for stealing customers’ property.
