Jean-Louis (Henri Vidal) makes his living by trapping deadly snakes and selling them to zoos. In love with shopgirl Simone (Francoise Arnoul), Jean-Louis gallantly comes to her defense during a minor skirmish with a policeman. Things get out of hand, and before long Jean-Louis is a fugitive from justice, leading the authorities on an appropriately serpentine chase through the streets of Paris. The film's "serpent" motif is further developed when Simone lands a job as a cabaret "snake dancer." If the viewer draws any analogies between Danger is a Woman and the story of Adam and Eve, then screenwriter Jacques Laurent (who adapted his own novel La Mort a Boire) has accomplished what he set out to do.
