1934. Philippe falls in love with Odile, a beautiful stranger, and decides to marry her, against the will of his parents. They would have preferred a more bourgeois bride, ideally from their own milieu: the paper industry in Angoulême. Isabelle, for instance, whom they have known since she was a child, would have been the perfect match. But Philippe sticks to his choice and marries Odile. At first the newly-weds are passionately in love, and the whole family looks forward to the birth of an heir for the Marcenat family. But in vain. Instead, Odile neglects her marriage and devotes herself to drawing, a gift she inherited from her father. Or is her rekindled interest in art classes more the result of her encounter with the charming but mysterious artist François Crozant? Philippe sense that he's losing his wife and becomes madly jealous of François. Meanwhile Isabelle, who's secretly in love with Philippe, is just waiting for the right moment.
