The year is 1920. Louise is 18 years old and living in Brittany. Her mother rejects her dreams of a different future for herself. Their complicated relationship grows even more bitter when two boys call Louise "the bastard of the Manor" and she seeks an explanation. In the village, Louise meets the new teacher, Rose. The instant friendship that blossoms between them leads Louise to ask Rose's help in independently obtaining the equivalent of a secondary school diploma.
