Vacation this year for Léa, Adrien and their little brother Theo, who was born deaf, is in Provence, staying with grandfather Paul, an olive-grower they have never met due to a family conflict. It's hardly their dream vacation, and is made worse the day before they leave by their father telling them he is moving out. Within twenty-four hours, there is bad blood between the teens and their grandfather, whom they consider an uptight control freak. Wrongly. Paul's stormy past resurfaces and the seventies make a comeback against the backdrop of the Alpilles hills. In the course of a turbulent summer, the two generations transform each other.
