In
Ancona, Giovanni is a therapist whose 17-year-old son, Andrea, is accused of stealing a rare
ammonite fossil from his school. Andrea is suspended and protests his innocence. However, he later confesses to his mother, Paola, that he and his friend stole it as a prank and intended to return it before it broke. Giovanni and Andrea make plans to go
jogging together, but Giovanni is called to the distant home of a patient who is severely distressed about a possible cancer diagnosis. Instead, Andrea goes
scuba diving with a friend and swims into an underwater cave, where he accidentally drowns. Giovanni, Paola, and their daughter Irene are left to mourn. Giovanni investigates the diving equipment model and becomes suspicious that Andrea's was defective. However, Paola reminds him that the verdict was that it was functioning properly. Giovanni, once a distant observer of his patients' struggles, begins having difficulty analyzing them, particularly the one he went to see on the day Andrea died, against whom he shows signs of impatience and hostility. One day, Paola receives a
love letter sent to Andrea by a girl named Arianna, whom he had met at a camp. The family does not know Arianna and never knew Andrea had a girlfriend. They realize she does not know Andrea has died and attempt to contact her, eventually inviting her to their home. Giovanni stops by a music store to buy an album, ostensibly for a friend of Andrea, but more for Andrea. A clerk gives him a
Brian Eno album. Arianna arrives on her way to a destination and sees Andrea's bedroom. She shows Giovanni photographs Andrea sent her of himself in his room, some of which are very amusing. The family welcomes Arianna and offers to host her in their home, but she informs them she is
hitchhiking with her friend Stefano to spend vacation in France. The family offers Arianna and Stefano a short ride, but it lingers to a point where they drive into the night and reach
Menton, on the border between Italy and France. Bidding Arianna and Stefano goodbye, the family watches their bus leave Italy and wanders on the beach as a new life awaits them. ==Cast==
