A pretty girl of 22 happens to be the present Duchess Gloriana, sovereign of a microscopic country in the Alps founded centuries ago by a roving band of English bowmen. Gloriana's unique solution to the near bankruptcy of her tiny domain is to declare war on the U.S.! There's some method to her madness, however, for her study of recent history suggests that the surest way to wealth today is to lose a war with the United States, for that country's odd reaction is to pour aid, relief and rehabilitation on the vanquished. When her "declaration" is considered a prank, Gloriana decides to escalate! Tully Bascomb, presently in charge of the bowmen, is to launch an attack so they can surrender and reap the rewards. Serious-minded Tully, however, upsets all calculations when he and his bowmen do the last thing expected—they win!
