Harvey Middleman (Eugene Troobnick), a New York fireman, lives a very ordinary life with his wife (Arlene Golonka) and children. After he rescues a beautiful girl (Patricia Harty) from a fire, he fancies himself to be in love with her, leaving his wife and seeking help, in the process, from a nutty Psychiatrist (Hermione Gingold).

In this wacky military spoof, Lemmon plays a terminally bored Army private waging a war of wits as he tries to throw a party under the nose of his obnoxious commanding officer.
