At twenty-four years of age, U.S. Army Ranger Sean Parnell was named commander of a forty-man elite infantry platoon, the 10th Mountain Division a unit that came to be known as the Outlaws. Tasked with rooting out Pakistan-based insurgents from a valley in the Hindu Kush, Parnell assumed they would be facing a ragtag bunch of civilians until, in May 2006, a routine patrol turned into a brutal ambush. Through sixteen months of combat, the platoon became Parnell's family. The cost of battle was high for these men. Not all of them made it home, but for those who did, it was the love and faith they found in one another that ultimately kept them alive."
