Harry Copeland, an elite paratrooper who fought behind enemy lines in Europe, returns home to run the family business. In a single, magical encounter on the Staten Island ferry, the young singer and heiress Catherine Thomas Hale falls for him in an instant, too late to prevent her engagement to a much older man. Harry and Catherine pursue one another in a romance played out in postwar America's Broadway theaters, Long Island mansions, the offices of financiers, and the haunts of gangsters.
