Éléonore is driving west when her car breaks down in the middle of Brittany, France. She rents a bungalow there in a campground with a view of the lake, in which, it is said, lives a legendary beast. From mobile home to mobile home, she observes the present, summons the past and lets herself be invaded by fiction.
