La Fin des étés (1964)

In this short fiction film, Marie has been living in the midst of a nightmare since the accident of Bernard, her brother. Clinging excessively to this handicapped being, she wants to take charge of it. Étienne, her fiancé, has no taste for sacrifice. He reproaches Marie for languishing in her adolescence. Love will prevail. In a definitive gesture, Marie will free herself from the bonds that still held her back to her childhood.
