In nearly a century, Sabine Weiss (1924-2021) has left behind a monumental and eclectic work: thousands of faces, collections of the greatest fashion designers in prestigious magazines, a Parisian working-class now disappeared, photoreports around the world… By focusing on the margins of society, she was an exceptional witness of the 20th century. For the first time, a film draws the portrait of this hard-worker artist and captures the last words of the greatest female figure of the Humanist photography (Robert Doisneau, Henri Cartier-Bresson).
