Fred Astaire finds a new dance partner in Joan Leslie in this delightful wartime musical. Fred portrays an ace with the highly regarded Flying Tigers squad. On leave in New York City on an eight-day furlough, Fred decides to forego any possible hero worship because of his uniform and dons civilian clothes. It so happens he meets and falls for Joan, a magazine photographer, and sets out to win her heart at all costs. The twist is that Joan is dedicated to the war effort and considers Fred - who is keeping his military role a secret - a never-do-well for not displaying any interest. But the pair are interested in each other and manage to set New York awhirl with some great dance numbers before Fred must return to the war torn skies.
