A biography of the dancer Isadora Duncan, the 1920s dancer who forever changed people's ideas of ballet. Her nude, semi-nude, and pro-Soviet dance projects as well as her attitudes on free love, debt, dress, and lifestyle shocked the public of her time.

In 1927, Isadora Duncan has become a legend as the innovator of modern dance, a temperamental bohemian, and an outspoken advocate of free love. 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 into paying her $300 so that she can take her family to England. Modeling her free-form style of dance and costume after Greek classicism, she rapidly acquires international acclaim. In Berlin, she meets her first love, Gordon Craig, a young stage designer who promises her that together they will create a new world of theater. After bearing the already-married Craig a daughter, Isadora moves to Paris and meets Paris Singer, a millionaire who lavishes gifts upon her and later buys her an enormous estate for her to open a School for Life, where only beauty and simplicity are taught. Following the birth of a son, Isadora returns to England with Singer but becomes bored with her quiet life and enters into an affair with her pianist, Armand. A short time later, both of her children are drowned when their chauffeur-driven car plunges off a bridge into the Seine. Broken by the tragedy, Isadora leaves Singer and wanders about Europe until in 1921 she receives an offer to open a dancing school in the Soviet Union. Unaffected by the country's poverty, she develops a strong rapport with the peasantry and has a passionate affair with Sergei Essenin, a volatile poet whom she marries so that he can obtain a visa to accompany her to the United States. Essenin's outrageous behavior turns a press conference into a shambles, however, and U. S. anti-Bolshevist sentiment turns to open hostility when Isadora bares her breasts during a dance recital in Boston. Following the disintegration of her marriage, she returns to Nice to write her memoirs. Impulsively selling her possessions in order to open a new school in Paris, Isadora goes to a local cafe to celebrate and spots Bugatti, a handsome Italiam whom she has been admiring for several days. She goes for a drive with him in his sports car, and as they roar along a road by the sea, Isadora's long chiffon scarf catches in the spokes of a wheel and strangles her.
