context: Anna, a modern day Parisian psychologist, is researching the cases of women who committed suicide in the 20th Century. She becomes fascinated by the story of Antonieta Rivas Mercado, a Mexican writer and social activist who committed suicide inside Notre Dame Cathedral in Paris. To find more about Antonieta's story, Anna travels to Mexico and interviews people who knew her. She receives her first clues about Antonieta's life from Juana, a Mexican librarian who frames the live of Antonieta Rivas Mercado within a stormy period of Mexico's history, the political turmoil of the 1910s-1920s.
  Antonieta's personal life was as dark and dramatic as that of her era. She was a daughter of a famous architect and as a child she posed for the golden angel atop the famous column of Independence in Mexico City.
  Vargas, a poet, now a middle-aged man, recounts for Ana the life of Antonieta when he met her and they were friends. The story moves back and forth between present and past.
  As a young woman, Antonieta married but left her husband and fell madly in love with the painter Manuel RodrÃ­guez Lozano. The painter was married and Antonieta's feelings remained unrequited because Manuel was homosexual. Their Platonic relationship lasted for several years during which she wrote him many lover letters, later published in a book.
  Leon, a Mexican historian, further illustrates Antonieta's life for Anna. Still in love with the painter, Antonieta meets JosÃ© Vasconcelos, a Mexican intellectual who is running for president of the country on the platform of offering education to the masses. Antonieta, is drawn into the idealist politician, becoming Vasconcelosâ lover and prime advisory.
  After Vasconcelos is politically defeated, she accompanies him in exile to Paris. They have lost their political idealism. She begs him to tell her if he still needs her. He replies that, really no one needs anyone, only God. Antonieta commits her last dramatic act, by pressing a pistol to her heart in the pews of Notre Dame.
