Based on the true story of the first American incursion into Afghanistan, and the New York Times #1 best seller by Marcus Luttrell, four Navy SEALs are dropped behind enemy lines to verify the whereabouts of a senior Taliban commander. Once located, they are to communicate his hiding place to headquarters, then call in to be picked up and returned to camp.

They come across an old man and three boys, and while knowing that it could jeopardize their lives, the commandos let the group pass. The act of mercy backfires, and soon the team is under attack by the Taliban army. With no clear escape, and no help from headquarters, Luttrell takes charge of the impossible mission. As they fight for their lives, they are quickly outnumbered and under heavy artillery. They must rely on their instincts and courage to get out of this hellhole alive.
