Madame − that’s Caroline. An elderly lady, who immediately makes it clear that there is more to her than just a coquettish hairstyle and bourgeois manners. The focal point of the movie is the relationship with her grandson, filmmaker Stéphane Riethauser. Madame is a double self-portrait, in which the matriarch and her gay grandson confide in each other. With humor but in a profound manner and with subversive force, the film deconstructs gender stereotypes and illustrates the saga of a middle-class family with archive pictures.
