After being told her mother doesn't qualify for a liver transplant, a disturbed teen attacks and injures a hospital nurse. When she's released from a mental hospital years later, she seeks revenge on those she blames for her mother's death.

A climate of civil war, a fight that has made them lose everything including their youth, four soldiers aged 13 to 20 years, will meet and build friendships. In the grip of an adult conflict, which they do not understand, Matéo, Dominique, Big Max and Kevin will keep recreating, round a pond and a cabin, a family.
