Writer Giovanni Pontano and his wife Lidia visit their seriously ill friend Tommaso Garani, a left-wing cultural critic, at a hospital in Milan. Giovanni's new book has just been published, and Tommaso praises his friend's work. Shaken by the sight of Tommaso in pain, Lidia leaves. Giovanni stays behind and as he leaves Tommaso's room, a sick and uninhibited young woman seduces him and they kiss. They are interrupted by the nurses, who slap the patient. Outside the hospital, Giovanni sees his wife crying but does not comfort her. As they drive off, he tells her about his "unpleasant" encounter with the sick woman and is confused when Lidia reacts with indifference. Giovanni and Lidia attend his book launch, where he signs books while she looks on from a distance. Lidia leaves and wanders the streets of Milan, ending up in the neighborhood where she and Giovanni lived as newlyweds. She comes across a street fight which she tries to stop, and later watches rockets being set off in a field. She later calls Giovanni and he picks her up. That night, they go to a nightclub, where they watch a seductive performance by a female dancer and engage in small talk. Lidia tells Giovanni that she has something to tell him but cannot say it now, and suggests they leave the club to attend a party thrown by Mr. Gherardini, a millionaire industrialist, at his villa. Giovanni socializes with the party guests while Lidia walks around in a state of boredom. Giovanni meets Valentina Gherardini, the host's young daughter. As they flirt, she slides her
compact across the floor, and soon others gather to watch the two compete at this game and place bets before Giovanni bows out. Meanwhile, Lidia calls the hospital and learns that Tommaso has died, leaving her devastated. Shortly afterwards, Lidia watches from the upper floor as Giovanni kisses Valentina. Mr. Gherardini meets privately with Giovanni and offers him an executive position with his company. Giovanni is reluctant to accept and leaves the offer open. While briefly reuniting with Lidia, Giovanni sees Valentina and follows her, leaving Lidia alone. A man named Roberto, who had been following Lidia, asks her to dance. A sudden rain shower sends the guests running for cover. As Lidia is about to jump into the pool from the diving board, Roberto takes her to his car and they drive off. She enjoys Roberto's company and their conversation but turns away from him as he tries to kiss her. Back at the party, Giovanni searches through the crowd and finds Valentina alone. She tells him to spend the rest of the evening with his wife. She plays him a tape recording of something she has written; Giovanni praises it, but she dismisses it and erases the tape. Giovanni states that he is going through a "crisis" common among writers, but in his case, it is affecting his whole life. They return to the party just as Lidia and Roberto return from their drive. Valentina invites Lidia to dry off in her room, where Lidia confronts her directly about her husband, but they soon engage in friendly conversation. As the women chat, Giovanni overhears his wife tell Valentina that she wants to die. Noticing Giovanni, Lidia declares that she feels no jealousy towards Valentina. Giovanni and Lidia leave the party at dawn. As Giovanni and Lidia walk away across Mr. Gherardini's private golf course, Lidia informs Giovanni of Tommaso's death. She recounts how Tommaso used to support her and offer his affections to her, but she eventually chose to be with Giovanni because she loved him. She then explains that she feels like dying because she no longer loves Giovanni. He acknowledges the failure of their marriage but reaffirms his love for her. Lidia takes out a love letter Giovanni wrote to her before they married and reads it aloud. Giovanni embraces and kisses her, but she resists, insisting that they no longer love each other. Giovanni continues to kiss and fondle Lidia in a
bunker on the golf course. == Cast ==
