This work tells about the personality of Marie Duplessis (a young Parisian woman who lived in Paris from 1824 until 1847), whom Alexandre Dumas Son looked at to create the character of Marguerite Gautier, the protagonist of his novel ‘The Lady of the Camellias’. Later, Marguerite became Violetta, the protagonist of Verdi’s ‘La Traviata’. This documentary aims to tell about the desires, conflicts and changes of Marie through the voice of three actresses; each one of them represents the real (Marie), literary (Marguerite) and theatrical (Violetta) sides of Marie herself, which contributed in the creation of a ‘myth’.
