After selling his ancestral estate, Archibald Colston decides to exchange the pastoral serenity of country society for a chance to make a new life for the Colston family in the wealthy elite of New York City. Upon their arrival, Archibald and his sister, Olivia, who is less than thrilled to be separated from the familiarity of English society, are thrown into the unbridled opulence of the New York winter season - but not without help. Millionaires might be made every day in the land of opportunity, but the old money is not so eager to welcome new money "Swells" into their exclusive circles. The Swells are ready for a showdown... and the opera is their chosen venue. Archibald and Olivia both find themselves with a vested interest in the successful opening of the Civic Opera House. With a show set to premiere on Christmas Eve, the future of the opera house, and a secure spot in society on the line, the pressure is high. Sparks will fly as the Colstons team up with a pair of eccentric producers, a spit-fire stage manager, a debutante with a golden voice, and a sensational corsetier to put on a show New York City won't soon forget.
