It stars an enormously sympathetic Andrew Garfield as Desmond T. Doss, the Seventh-day Adventist assigned as a medic to the 307th Infantry, 77th Army Division. The Virginia-born Doss refused to carry a gun owing to his religious beliefs. He was widely derided as a coward and a freak by his fellow enlisted men. (Vince Vaughn plays his sergeant, tormentor at first, protector in the end.) Then the truth about Doss was revealed, though it was there all along: Here was a man of true conviction and a bone-deep commitment to his religion's tenets. Doss ended up saving 75 lives in the Battle of Okinawa. In emotional terms, Doss was the reason the battle was won. And the war.
