Arco di trionfo (1948)

In the winter of 1938, Paris is crowded with refugees from the Nazis, who live in the black shadows of night, trying to evade deportation. One such is Dr. Ravic, who practices medicine illegally and stalks his old Nazi enemy Haake with murder in mind. One rainy night, Ravic meets Joan Madou, a kept woman cast adrift by her lover's sudden death. Against Ravic's better judgment, they become involved in a doomed affair.
