Authoritarian tenant Victor makes life impossible for Anselme, an old friend whose apartment he's shared since the death of his wife Louise. One day, after once again being humiliated in public by Victor, Anselme decides to take revenge.

Two old men, Anselme and Victor live together in an apartment of Paris. Victor has lost his wife 8 years ago, he is very bad tempered and he likes to annoy Anselme (they have discussions about the cheese or about a sausage). Then appears Anna Corelli, a vocalist and all together they have a repetition in the apartment. Victor becomes a tyrant and Anna leaves the apartment. Anselme doesn't know what to do with Victor. But the day comes when Victor visits the grave of his wife, Anselme arrives before him at the cemetery, lets a bouquet of roses and writes a message on the grave from a lover of Louise.—zutterjp48

One day, after once again being humiliated in public by Victor, Anselme decides to take revenge: he leaves an anonymous letter on Louise's grave.
