A remote military outpost in the mountains of Afghanistan is under Taliban siege. On any other day, the soldiers would fight back with full force, but a hailstorm limiting all visibility causes them to hold back. When the enemy takes advantage and gains ground, the soldiers must risk it all to fire off a missile from atop the base. Near Kandahar, a seasoned soldier directs a team of rookies under attack, only to discover four of his men stranded - without weapons - in the line of enemy fire.
