Marine Corps Sergeant John M. Stryker is a tough guy with an even tougher job-turn a platoon of raw
recruits into a combat-ready fighting machine. He pushes them mentally and physically to their limits -
with discipline, hard work and sometimes with his fists and they hate him for it, especially Pfc. Conway
(John Agar), the son of Stryker's former CO. Soon Stryker's lessons and their courage are put to the test
in a costly skirmish, but the worst is yet to come in one of World War II's fiercest battles, the taking of
Iwo Jima. Actual combat footage and the famous flag-raising scene on Mt. Suribachi highlight this
gripping human drama of heroism and conquest, brought to life by a superb supporting cast and Wayne
in one of the finest performances of his career.
