The third part of Krzysztof Kieslowski's trilogy based on the ideals embodied in the French national flag. When fashion model Valentine (Irene Jacob) accidentally runs over a dog, she takes him to a vet, gets him patched up, then tries to return him to his owner. It turns out that the owner is Joseph Kern (Jean-Louis Trintignant), a retired judge who lives alone and listens in on his neighbours' telephone conversations. Valentine and Joseph slowly become friends; meanwhile, one of Joseph's neighbours cheats on her boyfriend, a young law student who will have an important effect on Valentine's life.
