This documentary follows three parallel stories. First, that of the masterpiece, The Little Girl with the Blue Ribbon, this melancholic Renoir work with the "musical face" described by Henri Michaux. The painting was constantly tossed around, shelved by its patrons, looted by the Nazis, found by the Monument Men, recovered by the family, sold to a controversial collector, before finally arriving at the Kunsthaus Zurich. We also discover the painter's biography, and the eventful life of his model, Irene Cahen d'Anvers. Born into the Jewish upper middle class, this free and divorced woman long disowned the painting and left it to her daughter, who was murdered at Auschwitz. Discover the tumultuous journey of this painting, its model, Irene Cahen d'Anvers, and its connection to the dark hours of the Nazi regime.
