A long night brings back memories for Gabin and Solange. Separated by sickness and many years of living apart, will they have a chance at reuniting?

Gabin, an elderly man with Alzheimer's, remembers being in love. One winter's night, Solange falls down the stairs at her home. Waiting for dawn, she sees, passing before her eyes, the life she's spent on a farm in the Haut-Jura with her brother. Their father forbade them to marry so as to keep the land in the family.
