Lea, Adrian, and their little brother Theo, born deaf, go on holiday in Provence with their grandfather, Paul “Oliveron” they never met because of a family quarrel. It is not the holidays they dreamed, especially their father announced yesterday that he was leaving the house.

Because the turbulent past will resurface and Paul Seventies will land deep in the Alpilles. During this summer tormented both generations will be processed one by the other.
