Life is short and justice a rare commodity in the harsh wastelands of Afghanistan. Navy SEAL Lieutenant Rafe Stoner is about to encounter this cruel truth the hard way. An operation goes tragically wrong, and a Taliban sniper team ambushes a UNHCR ambulance. One of the dead is the woman with whom he intended to start a new life. Stoner turns his back on civilization, and begins a new career as a gun for hire in the bitter land ruled by the bomb and the bullet.
With a growing reputation as a man who gets results, the former SEAL agrees to locate the murderer of a young boy's father. This time he is up against overwhelming odds, so he recruits a former friend, Greg Blum, as an extra gun. Blum is a talented shooter, the son of a Russian who fought in Afghanistan during the Russian invasion. He is also the man Stoner once threatened to kill.
The operation becomes a desperate fight for survival. Battling drug-traffickers, murderers and warlords, Stoner has to employ all of his SEAL skills just to stay alive. The two men fight their way through ambush and the bitter snows of winter to reach their target. Standing in their way is a vicious warlord, Massoud, who counts among his ranks a psychopathic American sniper. The battle becomes a bloody and ferocious duel to the death.
