Hacksaw Ridge is an Academy Award winning film by Mel Gibson that tells the extraordinary true story of Seventh-day Adventist Desmond Doss (played by Andrew Garfield) who, in Okinawa during the bloodiest battle of WWII, saved 75 men without firing or carrying a gun.
He was the only American soldier in WWII to fight on the front lines without a weapon, as he believed that while the war was justified, killing was nevertheless wrong. As an army medic he single-handedly rescued the wounded from behind enemy lines, braved fire while tending to soldiers and was injured by a grenade and hit by snipers. Doss was the first conscientious objector awarded the Congressional Medal of Honour, which is the highest military honour in the US, awarded for personal acts of valour above and beyond the call of duty.
NOTE: This graphic film hides none of the horrifying realities of being on a battlefield and is rated MA15+ "Strong battle violence, blood and gore".
