They form a couple that you don't forget: Inspector Georges Vallois (Jean Gabin) and Lucky Fridel (Nadja Tiller), the latter being a former miss Austria. Her beauty and her charm change the mind of the inspector and turn him away from his duties. There is a game of attraction and repulsion between both as never seen in French cinema. He could be her father. There is a scene where Vallois answers tho her father that she could end up in prostitution if her father does not give her money anymore. Does Valois feel pity for her? The novel by Jacques Robert inspired the experienced director Gilles Grangier to this movie with a peculiar ending. Also Thérèse Marken (Danielle Darieux) give the dialogues between her and Vallois a captivating tension. Vallois is a bit Maigret-like but he has his own touch and is more human. It is also remarkable that the writer Jacques Robert adapted later a novel of Georges Simenon for the screen (Maigret voit rouge). This movie has kept all its freshness after those years but the problem of junkies has still grown more.
