Eighteen years after her death, a poignant portrait of the formidable actress that was Marie Trintignant. No documentary has ever been devoted to the career of Marie Trintignant, whose tragic death at the hands of her partner unfairly overshadowed her career. In the form of a letter addressed to her daughter, Nadine Trintignant offers, eighteen years after her death, an intimate, fair and deeply moving portrait of this free-spirited and stubborn child of the ball, who, by starring alongside Patrick Deweare, Isabelle Huppert and Marcello Mastroianni, and shooting under the direction of Alain Corneau, Claude Chabrol, Pierre Salvadori and Samuel Benchetrit, left her burning imprint on cinema and theater alike. Archival footage, film and stage extracts provide a luminous of the all-too-short life of this energetic woman, mother, actress and author.
