L'Île aux oiseaux(1988)

On a stormy night, off the coast of the Arcachon basin, a small sailboat named "Julie" disappears with a young girl of the same name on board. What really happened? The mystery is all the thicker because a month later, her husband met the same sad end. A year later, on the anniversary of Julie's disappearance, a commemorative meal is organized by the young woman's main relations. Many things from the past will then resurface.
