Is the relationship between Lucie (Christine Brucher) and her prim, pedantic and fussy husband (Francois Chattot) irreparably ruined, or is she only just bored by daily life with such a tedious man, and also somewhat comforted by it? In this romantic drama, based on a short story by the great existentialist philosopher Jean-Paul Sartre, Lucie tests the waters by having a fling with another man (Christian Izard) on the advice of a friendly shopkeeper. Meanwhile, her husband is treating her to such intimate kindnesses as scolding her for her mental sloppiness in watching television without consulting the channel guide.
