Vincenzo, a railwayman who works on the Rome-to-Paris line, has a wife in Italy and a mistress in France: Ginette, a widow with a four-year-old daughter. When he's offered a job in Paris he decides to move, but unfortunately his wife and petulant brother-in-law insist on accompanying him to Paris, and he must decide between the two women in his life.
