Walter Mitty (Kaye) is an "inconsequential guy from Perth Amboy, New Jersey". He is henpecked and harassed by everyone in his life including his bossy mother, his overbearing, idea-stealing boss Bruce Pierce, his dimwitted fiancée Gertrude Griswold, Gertrude's obnoxious would-be suitor Tubby Wadsworth and her loud-mouthed mother, Mrs. Griswold.
