Directed by Mel Gibson, Hacksaw Ridge is a faith-based movie that tells the true story of Desmond T. Doss, a medic in World War 11 and, because of his Christian faith, Doss fought as a conscientious objector. Tagged a "coward" and constantly prodded by military commanders to "go home", Desmond hung tough and stayed, going on to save 75 lives. He found the injured men following the battle at Hacksaw Ridge, and lowered them to safety by rope, facing great danger every time. He kept praying each moment after saving one, "Lord, just give me one more," and then he prayed this way again and again, until he had saved the 75.

Doss was a Seventh-day Adventist, and his conscience was guided by a framed poster of the Ten Commandments and the Lord's Prayer, one his father had purchased where Doss grew up in Lynchburg, Virginia. An image on the poster of Cain holding a club above his dead slain brother, Abel, is an image Doss never forgot. He asked himself how a brother could do that to his sibling.

According to the book, Hero of Hacksaw Ridge, written by Booton Herndon, the men of the 77th infantry told him, "When we go into combat, Doss, you're not comin' back alive. I'm gonna shoot you myself!" They added, "You're nothing but a coward!" But Doss stuck to his firm belief that his mission was not to kill, but to heal. His fellow soldiers changed their minds after being rescued by him and seeing how he put himself at great personal risk.
