Recounts three stories inspired by the three colours on the French flag, and each of the concepts the colours represent: liberty, equality, fraternity.
Julie (Juliette Binoche), wife of the famous composer Patrice de Courcy, must cope with the death of her husband and daughter in an automobile accident she herself survives. While recovering in hospital, Julie attempts suicide by overdose, but cannot swallow the pills. After being released from hospital, Julie, who it is suggested wrote (or helped to write) much of her husband's famous pieces, destroys what is left behind of them. Calling Olivier (Benoît Régent), an unmarried collaborator of her husband's who has always admired her, she spends a night with him and says goodbye. Emptying the family house and putting it up for sale, she takes an apartment in Paris near Rue Mouffetard without telling anyone, her only memento being a mobile of blue beads that the viewer assumes belonged to her daughter.
After opening with a brief, seemingly irrelevant scene of a suitcase on an airport carousel, the story quickly focuses on a Paris divorce court where Karol Karol (Zbigniew Zamachowski) is pleading with the judge — the same legal proceedings that Juliette Binoche's character briefly stumbled upon in ''Blue''. The immigrant Karol, despite his difficulty in understanding French language, is made to understand that his wife Dominique (Julie Delpy) does not love him. The grounds for divorce are humiliating: Karol was unable to Consummation the marriage. Along with his wife, he loses his means of support (a beauty salon they jointly owned), his legal residency in France, and the rest of his cash in a series of mishaps, and is soon a beggar. He only retains a 2 French franc coin.
Valentine Dussaut (Irene Jacob) studies at University of Geneva and works as a part-time model. She regularly attends ballet classes. She calls her possessive boyfriend in London and plans to meet him. During her part-time job as a model, she poses for a chewing-gum campaign and the photo selected is one of her looking very sad. While walking back home, Auguste (Jean-Pierre Lorit), a student neighbour of Valentine's, drops his textbooks and one book falls open at a particular chapter of the Criminal Code, which he notes. Driving back to her apartment, Valentine is distracted and accidentally hits a German Shepherd dog. She tracks down the owner, a retired judge, Joseph Kern (Jean-Louis Trintignant), who seems unconcerned. Valentine takes the dog, Rita, to a veterinarian, where she learns that the dog is pregnant. She overcomes the sexual advances made by the ad company's photographer. Later, money is delivered to her apartment from an unnamed sender.
