When Lau joins the training academy for new police recruits he goes through vigorous training sessions. The leaders in the police academy picks out another new recruit, Yan, as being the best of the bunch and Yan is soon sent to infiltrate the Hong Kong Triads.
Ten years later the police, led by SP Wong, are closer than ever in arresting Sammy and his Triad group. The mole that the police planted within the triad organization, Yan, has now moved up within their ranks to become one of Sammy’s most trusted henchmen. Sammy and his gang are set to complete a deal that night with a group of Thai drug dealers. As the drug deal starts to take place, Yan the undercover police officer, taps morse code into a hidden microphone for SP Wong to hear. As SP Wong gets Yan’s messages, SP Wong orders his group of police officers to take the appropriate actions. Unknown to everybody, except Sammy, the mole that Sammy placed into the police organization, Lau has now worked his way up in the police organization and is now part of SP Wong’s police task force. While, Yan, relays real time information on the drug deal to SP Wong, Lau relays real time information to Sammy. A deadly game of cat and mouse occurs as both sides discover that there is an informant in each of their groups.
