It is 1938 and fascist Italy has imposed its infamous race laws. A young Jewish professor entertains a tormented passion for the beautiful and enigmatic Sonia. She is everything that he is not: the privileged daughter of a family that is wealthy, prominent, and above all, gentile. He wins her affections, but the price is great. He must deny his origins in order to enter that jealously guarded circle of intimates composed of her family and their friends. It is a world that has no use for him and forces him into humiliating and painful compromises.
