Having been discharged from the Marines for a hayfever condition before ever seeing action, Woodrow Lafayette Pershing Truesmith (Eddie Bracken) delays the return to his hometown, feeling that he is a failure. While in a moment of melancholy, he meets up with a group of Marines who befriend him and encourage him to return home to his mother by fabricating a story that he was wounded in battle with honorable discharge. They make him wear a uniform complete with medals and is pushed by his new friends into accepting a Hero&#39s welcome when he gets home where he is to be immortalized by a statue that he doesn&#39t want, has songs written about his heroic battle stories, and ends up unwillingly running for mayor. Despite his best efforts to explain the truth, no one will listen.
