A father and his teenage daughter live, work and love in their own way in a remote tree nursery in the South of France. The mother disappeared a year ago. It's summer. Hugo and Lucie are absorbed by the needs of the trees and plants. But this absence has also strengthened the reassuring but dangerous bond between them. Akim, a young illegal worker, who lends a hand from time to time, tells Lucie of a possible life elsewhere. Then, one day, Sonia, the truant mother returns.
