Hartman (Richie Ren) is renowned as the top shooter in the police force but he hides a secret past - his former teammate and superb marksman Lincoln (Huang Xiaoming) was jailed for a mysterious case of accidentally killing a hostage and has now just been released. With only vengeance in his mind, Lincoln takes on Hartman and the police, believing they betrayed him. When a high-security prisoner transfer is sabotaged by an unknown sniper and a high profile convict escapes, young upstart OJ (Edison Chen), the hot-headed rookie on the team, surprises everyone by accurately replicating the suspect's impossible shots. A battle of wits ensues as OJ becomes fascinated with Lincoln's skills yet bound by Hartman's rules.
