In February, 1945, one of the fiercest battles of the Pacific theater of World War II occurs on the tiny island of Iwo Jima. Thousands of Marines attack the stronghold maintained by thousands of Japanese, and the slaughter on both sides is horrific. Early in the battle, an American flag is raised atop the high point, Mount Suribachi, and a photograph of the raising becomes an American cause celebre. As a powerful inspiration to war-sick Americans, the photo becomes a symbol of the Allied cause.
