Valentine Dussaut is a student at the
University of Geneva who works part-time as a model. She often contacts her possessive boyfriend Michel, who is currently in England. During a photo shoot for a chewing gum advertising campaign, the photographer instructs Valentine to look sad as she poses against a red background. While walking home one night, Auguste Bruner, Valentine's neighbour and a law student, drops his textbooks, one falling open to a particular chapter of the
Criminal Code. While driving home that same night, Valentine accidentally runs over Rita, a pregnant
Malinois dog. She tracks down the dog's owner, a reclusive retired judge named Joseph Kern. When he shows no concern, Valentine takes Rita to a veterinarian and decides to keep her. She selects her favourite photo at the studio, rebuffing the photographer's sexual advances. Valentine later receives a sum of money from an anonymous sender at her apartment. The next day, Valentine takes Rita for a walk, and the dog leads her back to Joseph's house. Joseph confirms that he sent the money for the veterinary expenses and tells Valentine to keep the dog. Inside his house, she catches him eavesdropping on a male neighbour's phone conversation with his male lover. She urges Joseph to respect his neighbour's privacy; he challenges her to reveal the eavesdropping to the neighbour. Valentine goes next door to do so, but leaves without denouncing Joseph after discovering the neighbor leads a straight life with a wife and seeing that the neighbour's daughter is listening on the phone extension. Joseph tells Valentine that their actions will not affect the outcome of these people's lives. This reminds Valentine of her teenage brother, who discovered that he is not his father's biological son. Joseph plays Valentine a phone conversation between Auguste and his girlfriend Karin. From his window, Joseph and Valentine observe another male neighbour, whom Joseph suspects is a heroin dealer, which upsets Valentine. When Joseph correctly deduces that Valentine's brother is a heroin addict, she declares that she pities Joseph and leaves. That night, Joseph writes letters to his neighbours and the police confessing his spying activities, resulting in a
class-action lawsuit. Meanwhile, Auguste passes his exam to become a judge, crediting his success to the dropped textbook. Auguste's first case as a judge is Joseph's trial. At court, Joseph sees Karin meeting another man. Joseph later reveals to Valentine that he turned himself in to see if she would come back. Valentine discusses her upcoming trip to England to visit Michel; Joseph suggests that she take the ferry. Joseph recounts a case where he wrongly acquitted a sailor. When Valentine asks about Joseph's love life, he evades the question and discusses a recent dream in which Valentine was happy. Unable to reach Karin by phone, Auguste climbs up to her flat and catches her having sex with another man. He takes his anger out on his dog by leaving it tied to a lamppost. Joseph calls Karin's personalised weather service to inquire about the weather for the
English Channel next week, which she predicts will be clear. Karin plans to sail there soon with her new boyfriend, who owns a yacht. The day before Valentine leaves for England, she invites Joseph to her fashion show. Afterwards, Joseph elaborates on his dream with Valentine, in which she was 50 years old and happy with an unidentified man. He then reveals that the woman he loved died in an accident after he followed her across the English Channel. His last case as a judge involved his ex-girlfriend's lover. Before parting ways, Joseph and Valentine plan to meet again in three weeks, when he will give her one of Rita's puppies. Valentine boards the ferry to England. Auguste also boards the ferry, reunited with his dog. The next morning, Joseph learns that a storm has hit the English Channel, causing both the ferry and the yacht with Karin and her boyfriend to sink. Watching the television coverage of the incident, it is revealed that only seven survivors were rescued: a barman, Julie and Olivier (from
Blue), Karol and Dominique (from
White), Auguste (without his dog), and Valentine. Upon seeing the news, Joseph is relieved. The freeze frame of Valentine's face on the news coverage mirrors that of the chewing gum photograph. ==Cast==
