One day they meet at the airport and decide to spend the evening at a nightclub, ending up at her apartment where they make love. Later that week, Pierre and Nicole travel to Reims where Pierre is scheduled to present a showing of the 1952 documentary film about André Gide at a conference. They check into the Hotel Michelet before Pierre heads over to the theatre. After Pierre takes to the stage, Nicole arrives without a ticket and is forced to wait in the lobby during his speech. Afterwards, Pierre's friend insists on having a drink before Pierre returns to Paris. As they leave, Pierre ignores Nicole who has been waiting in the street. When his friend invites himself to accompany him back to Paris, Pierre sneaks back to the hotel where an upset Nicole tells him he should leave without her. He apologises and they decide to leave. After driving through the night they find a romantic cabin. The next day, Pierre and Nicole enjoy their time together taking photographs. Their happiness is cut short, however, when Pierre calls his wife to tell her he had to stay in Reims overnight. Having called Reims the previous night, Franca suspects he's lying and hangs up in anger. After driving Nicole home, Pierre faces his wife and they argue. Franca accuses him of having an affair and Pierre walks out of their apartment, spending the night sleeping in his office. The following morning, Franca calls him at the office informing him that she will never forgive him for walking out on her and that he'll be contacted by her divorce lawyer. Pierre goes to Nicole's apartment, but she is unable to talk because her father is about to visit. Pierre passes her father on the stairwell as he's leaving. Back at his apartment, Pierre and Franca discuss their divorce and Franca falls apart, sometimes hitting him and at other times begging for his forgiveness. They make love, and afterwards she asks if he will be coming back. He tells her it would never work out with all that's happened. She slams the door behind him. Overcome with depression, Franca is comforted by her friend Odile, who throws away the sleeping pills she finds in the bathroom fearing her friend may attempt suicide. Later that week, Pierre and Nicole have dinner and argue after Pierre gets annoyed and embarrassed by her talking
