A charming, starry-eyed Czech immigrant arrives in America expecting the golden land of opportunity. What he discovers instead, in this breezy comedy, are the harsh realities of New York City. Ginger Rogers stars as Sylvia Dennis, a bouncy chorus girl who comes to the aid of Karel Novak (Francis Lederer), a lonely and somewhat lost illegal alien who just jumped ship to find his dream in America. But the dream turns sour when he takes the job of a scab driver during a taxi-cab strike and gets a punch in the nose for his trouble. Sylvia, taking pity on Karel and enchanted by his undying optimism, allows him to camp on the roof of her apartment building - a situation that sparks romance against the backdrop of the glittering Manhattan skyline.
