When stationmaster Roubaud realises his young wife Séverene was once her rich godfather's mistress he reacts violently, luring him onto a train journey to murder him making sure Séverene watches to incriminate her too.
Séverene suggests Jacques kill Roubard so they can escape but Jacques is hiding his own secret - moments of mental fugue which render him psychotic.
Renoir's masterly direction and great performances from Jean Gabin, Simone Simon, Ledoux and Carette make this a classic of French cinema.
