In this film full of surprises, Juliette Gréco, almost 85, the great lady of French chanson, Saint-Germaindes-Prés's emblem and icon of existentialism, delivers with astonishing frankness, revealing herself both funny, pertinent and incisive, having fun at the game of "Undress Me" without taking himself seriously. She evokes the memories of her love affairs, her passion: Boris Vian, who made her speak, Jean-Paul Sartre, who launched her into the song, or Marguerite Duras, who dragged her into the communist adventure. She also talks about her torrid affair with Miles Davis, her relationships with the Hollywood producer Darryl Zanuck, the “400 coups” she made with Françoise Sagan, or her marriage to Michel Piccoli.
