The Unburdening(1983)

Original title: L'Allégement

In this surreal, overstated, black-and-white film by Marcel Schuepbach, a young woman is slowly driven to near insanity by an inner desire for a passionate existence, while she lives a dull life at her grandmother's country home. The grandmother recalls how her own daughter lost hold of sanity and died on her lover's grave -- and she begins to see similarities in her granddaughter's behavior.
