Now past 40, she lives in poverty in a small hotel on the French Riviera with her companion Mary Desti and her secretary Roger, to whom she is dictating her memoirs. As a young girl in California, Isadora first demonstrates her disdain for accepted social standards by burning her parents' marriage certificate and pledging her dedication to the pursuit of art and beauty. In 1896, she performs under the name of Peppy Dora in a rowdy music hall in Chicago and publicly embarrasses the theater manager.
