In 1945, World War II was drawing to a close. As an important member of the Axis of Evil, Japan's arrogance had become a spent force. That year, the Battle of Okinawa, which determined the direction of the war, kicked off. Thousands of high-spirited American soldiers were sent to Okinawa, waiting for them at the Hacksaw Ridge, which was heavily defended by the enemy and extremely dangerous. Among this group of people, there was a military doctor who was unwilling to take up arms. His name was Desmond Doss (Andrew Garfield), from Virginia, USA. When the Pacific broke out, the thin Desmond volunteered to become a military doctor to save the dying and heal the wounded and enlisted in the army. However, due to his childhood and family reasons, he was always unwilling to take up guns for training, and would rather bear the charge of refusing to serve in the military and be sent to a military court. After many twists and turns, Desmond finally came to Hacksaw Ridge with his comrades. In the hail of bullets, countless people fell to the ground in an instant. With the support of faith and conviction, Desmond saved dozens of dying lives by himself... This film is based on a true story.
