A woman walks down an empty street at night and she notices that she is being followed by a taxicab. The driver convinces her to get in the car alleging that it is dangerous for a woman to be alone in the area. At dawn the taxi is hit by a train, on a level crossing in the countryside. The driver is found dead in the morning; his name was Jean-Paul Louvain, 47, and he was married. Commandant Angeli discovers that Louvain was killed before the impact.
