Versailles

Tired of the social services system she can't negotiate, homeless Nina is a loving but inadequate mother to 5-year-old Enzo. Chancing upon Damien in his shack in the Versailles woods, she does a runner after one night, leaving Enzo so she can put her life in order. Though largely controlled by his id, Damien grows close to the boy; as winter comes he returns to his estranged father to give Enzo a home. (Variety.com)
