During World War Two, hard-bitten sergeant John M. Stryker (John Wayne) earns the enmity of the recruits he trains for action in the Pacific. New recruit Peter Conway’s (John Agar) dislike for his commander turns to respect, however, when the latter saves him from a grenade. The squad are forced to show their mettle when they are sent into Iwo Jima to take Mount Suribachi whilst under constant fire from the Japanese. John Wayne’s performance earned him his first Oscar nomination.
