While on a mission, sniper Jin Ming (Michael Tung) is distracted by a captive child and disrupts the operation. Ten years later, the child Jin Ming takes under his wing and names Jin Tai (Henry Prince Mack) grows up to become a sniper himself, just like another girl Jin Ming rescued, Xiao Mei (Frida Hu). During the next task, Jin Ming suddenly falls under suspicion, and then the paths of his “children” diverge – Xiao Mei unconditionally takes the side of the “father” and, together with him, arranges a massacre at the headquarters, and Jin Tai, who is “in the field”, tries to stop them.
