Hartman Fong (Richie Jen) succeeds Shane (Bowie Lam) as the leader of Hong Kong's Special Duties Unit Sniper Team. Hartman who is by-the-book and hierarchical, got the job despite being the second best shooter in team history. The best was Hartman's former teammate Lincoln (Huang Xiaoming), whose unorthodox methods and confidence makes him arrogant and disdainful of authority. Hartman and Lincoln are two alpha males with a long-running rivalry, with only room at the top for one sharpshooter.
