Aching to escape her dull duties as daughter of the U.S ambassador to France, Joan Fisk (Olivia de Havilland) sets out to demonstrate a point to her father and his small-minded friends in this genial comedy. Deeming all American servicemen wolves, a U.S. senator (Adolphe Menjou) wants to put Paris off limits to them. To prove him wrong, Joan begins a harmless fling with a young American soldier (John Forsythe) -- but ends up falling in love.
