To the Shores of Tripoli

When a carefree playboy (John Payne) joins the Marine Corps, he tests the skill and patience of the tough veteran sergeant (Randolph Scott) who tries to whip him into a real Marine. But, as his training proceeds, the recruit's cocky selfishness is replaced by selfless valor, and he eventually earns the love of a beautiful Navy nurse (Maureen O'Hara).
