Plot synopsis: In this French crime film, set during the time of the Gulf War, an elderly German tourist is murdered in Paris by junk dealer Joseph Katz (Pinkas Braun), a friend of Paris detective Sam Bellamy (singer Patrick Bruel). Romantically involved with the victim's daughter Emma Guter (Isabella Ferrari), Bellamy covers up the crime he witnessed. Joseph then mysteriously vanishes, and Bellamy heads for Berlin where the victim's possessions are auctioned. After Bellamy finds the source of the well-hidden traffic in art stolen by Nazis from French Jews, he discovers a Nazi war criminal is blackmailing past associates. Incorporating background from journalist Hector Feliciano's Lost Museum, the film is adapted from Guy Konopnicki's novel, Pas de Kaddish pour Sylberstein (No Kaddish for Sylberstein).
