Green Boys could be a "Little Prince" of the millennium of exile. Alhassane, 17 years old, left Guinea and arrived alone in France after an arduous journey. Welcomed in a village in Normandy, he meets Louka, 13 years old. Between the two boys a friendship is born and is invented day after day. What separates them binds them as much as what unites them. During the summer, they build a hut on the cliff overlooking the sea. As a zone of freedom, it will be a secret place of childhood and a refuge from wounds.
