Twelve-year-old Léa would have preferred to live with another family.
A family where the parents haven't separated, where there aren't two houses... A family where her mother would understand her better, where her father would have his feet firmly planted on the ground, and where her younger ecologist brother wouldn't reproach for spending so much time in the shower on the pretext that there'll soon no longer be any water on the planet.
In this particular year, Léa is entering her second year of secondary school. While her father and mother try to construct their lives, she falls in love for the first time. The experience will shake up her convictions about the world and her parents, and she will never truly be the same again.
In this particular year, everyone will slowly recover their equilibrium and open themselves up to others.
