True-life account of the military career of Audie Murphy, the most decorated soldier in WWII. Native of Texas, he was placed in charge of his many younger siblings on the death of his mother and decided to join the military at the age of 18 to provide for them. His many acts of bravery and heroism during the US military advance through Italy, France and into Germany earn him increasing rank and responsibility as well as the respect of his comrades in arms. Eventually he receives two dozen of the highest medals the US and France can bestow, culminating in the awarding of the Congressional Medal of Honor.

In 1945, the Marines attack twelve thousand Japaneses protecting the twenty square kilometers of the sacred Iwo Jima island in a very violent battle. When they reach the Mount Suribachi and six soldiers raise their flag on the top, the picture becomes a symbol in a post Great Depression America. The government brings the three survivors to America to raise funds for war, bringing hope to desolate people, and making the three men heroes of the war. However, the traumatized trio has difficulty dealing with the image built by their superiors, sharing the heroism with their mates.
