Walter Mitty, a daydreaming pulp-fiction proofreader living under the thumb of his overprotective mother, often escapes into heroic fantasies. His imagination becomes reality when he encounters a mysterious woman, Rosalind van Hoorn, who entrusts him with a little black book. She claims the book contains the secret locations of the Dutch crown jewels, hidden since World War II.
