Constance is a young French woman dissatisfied with her mundane life but has a talent for reading stories to others. As the movie opens, she reads a book called La Lectrice to her boyfriend, in which the main character, a woman named Marie, reads literature to others for a living. She becomes engrossed in the book to the point that she begins imagining herself as Marie: Constance and Marie are played by Miou-Miou, and the movie weaves back and forth between their stories.
Marie embarks on her new profession with gusto. As she reads to her clients, all of whom are seeking a little more than the solace of literature, she works a fantastical transformation on them. Her clients include the widow of a Marxist general (María Casares), a nervous businessman (Patrick Chesnais), a retired magistrate, and a handicapped teenage boy. Soon the clients' friends and families become involved, as does her professor (Christian Blanc). The general's widow's maidservant and the boy's friends from school become affected by the readings, and Constance has an affair with the businessman. Books read include The Lover (by Marguerite Duras, read to the sexually frustrated businessman), and the works of Marquis de Sade (read to the judge and his libertine friends).
