Leo, a 12-year-old orphan in the care of social services, struggles to fit in with the families he is placed with. Social services give him one last chance by placing him with the Dumont family, who live on an isolated farm in Haute-Provence, until he reaches adulthood. But Léo quickly realizes that this foster family is very different from the others: Jacques, the father, tyrannizes his wife and son. His arrival proves to be a real challenge for this drifting couple: for one, it is the hope of a new beginning, and for the other, yet another obstacle. Léo also befriends the son, Thomas, much to the chagrin of Jacques, who will do everything he can to separate them, to the point of becoming their common enemy...
