U.S. Navy SEAL Chris Kyle has a single task during his deployment in Iraq: to protect his comrades. His outstanding marksmanship saved the lives of countless soldiers on the battlefield, and when the reports of his brave deeds made the rounds, he earned the nickname "Legend". But his name also becomes known on the side of the enemy: When a bounty is placed on his head, he is targeted by the insurgents. He has to fight a completely different battle on the home front: How is he supposed to prove himself as a husband and father when half the world is between him and his family? Despite the danger and the grave impact on his loved ones back home, Chris proves himself on four gruesome missions in Iraq, personally standing up for the SEAL's motto that "no man is left behind." But when he finally returns to his wife Taya Renae Kyle and his children, Chris realizes that it is the war that he cannot leave behind.
