A major stock exchange in the world, Hong Kong attracts not only money but any who try to manipulate the market. At the Hong Kong Police Force Commercial Crime Bureau, an operation is underway to infiltrate a trading company, Feng Hua International where a man, nicknamed "Boss" is the chief suspect. The team, led by Inspector Leung (Lau Ching Wan) together with Yeung (Louis Koo) and Lam (Daniel Wu), installs interception devices to monitor the company's communications. When crucial information on a surging share is intercepted, a moment of greed leads the team into a cross fire between the Bureau and the boss.(source:Wikipedia)
