It’s summer, on the beach of this little town in Brittany, a man is building a sand castle. A few people watch him. We will be told the story of three of them: a boy, Jumbo, aged 9; François and his sister Zaza. All of them had to deal with the death of somebody they cherished.

Following a psychedelic experience, two young women, Mathilde and Léa, embark on a roadtrip across France that takes them to the farthest reaches of Brittany in search of the Druids, via the Black Valley of Berry and its sorcerers.
