In turn-of-the-century America, a young girl dreams of a world that stretches beyond the confines of a quiet life on the family farm. With little more than her wit and a cigar box of treasures to call her own, Mable steps away from all she knows, seeking the limitless marvels of the Chicago World's Fair. There, a chance encounter triggers her destiny--a life with a famed showman by the name of John Ringling. A quarter of a century later, Lady Rosamund Easling of Yorkshire, England, boards a ship to America as a last adventure before her life is planned out for her. There, the twenties are roaring, and the rich and famous gather at opulent, Gatsby-esque parties in the grandest ballrooms the country has to offer. The Jazz Age has arrived, and with it, the golden era of the American circus, whose queen is none other than the enigmatic Mable Ringling. When Rosamund's path crosses with Mable's and the Ringlings' glittering world, she makes the life-altering decision to leave behind a comfortable future of estates and propriety, instead choosing the nomadic life of a trick rider in the Ringling Brothers' circus.
