Sharpshooter Hartman (Richie Jen) runs a tight ship as head of the SDU sniper team, but hotshot rookie OJ (Edison Chen) keeps questioning his authority and training regiment and even takes pointers from Hartman's rival, former top sniper Lincoln (Huang Xiaoming). An arrogant ace whose shooting skills surpassed Hartman, Lincoln has just been released from prison after serving time for accidentally shooting a hostage, and he wants revenge. In a blatant challenge to Hartman and the police, Lincoln helps crime boss Tao (Jack Kao) escape from custody, paving the way for a deadly showdown between the snipers.
