Carlo, 21 years old and exempted from military service, is spending the summer in his father's empty villa and relaxing with friends in
Riccione, a seaside town untouched by the war. When a German aircraft flies low over the beach, people panic and Carlo comforts a frightened little girl. She is reclaimed by her mother Roberta, a 30 year old widow of a heroic naval officer. Carlo and Roberta are attracted to each other and he asks her out, taking her for a trip to the neutral state of
San Marino, although he has a girlfriend, Rossana. Roberta's mother warns her to avoid him because his father is a vicious
Fascist party boss and his mother was a promiscuous film actress. Roberta's younger sister-in-law Maddalena arrives as a refugee from the fighting in the south, and Roberta asks Carlo's friends to let her join them. They all go to a circus, which is interrupted by an air raid, so Carlo asks everybody back to his father's villa. In the blackout, couples dance to the music of
Temptation. Hesitant at first, Roberta eventually ends up in the garden in the arms of Carlo, and they kiss, caught by Rossana. When news comes of the
fall of the Fascist regime, jubilant citizens sack the party headquarters, toppling the bust of
Mussolini. Carlo's father flees and the villa is requisitioned to house refugees. Carlo and Roberta spend the night making love on the deserted beach. When she returns home, both Maddalena and her mother express their disapproval of the affair, to which she replies, that nobody had cared when she was married to an older man, and that for the first time in her life she is happy. Maddalena refuses to stay in Roberta's and her mother's villa any longer and leaves town. Meeting again on the beach after curfew, Carlo and Roberta are arrested by an army patrol, who discover that Carlo's exemption has expired. They release him on the promise that he will report for service at
Bologna next day. Roberta, afraid to lose Carlo, persuades him to come with her to her empty villa in
Rovigo and hide from the draft. The reluctant Carlo explains that his place had always been with the crowd, but eventually gives in. Their journey is interrupted by an air raid, and due to the damage, all trains are cancelled except those heading back south. Roberta enters the train back to Riccione, where she left her daughter. Carlo stays behind, trying to make her understand why he must stay. He expresses his hope that they will meet again, but Roberta replies that she is convinced that their parting is final. ==Cast==
