John Payne plays Chris Winters, a wealthy, wise-lipped young Marine recruit who learns the true meaning of "Semper Fidelis" the hard way, courtesy of tough-as-nails drill sergeant Dixie Smith (Randolph Scott). Chris also falls in love with Navy nurse Mary Carter (Maureen O'Hara in her first Technicolor appearance), which leaves his poor hometown sweetheart Helene Hunt (nacy Kelly) in the lurch. By film's end, Chris is one of the Few and the Proud as he and his buddies are shipped off to combat overseas.
