In a fictionalized futurist world, a new law allows distressed parents to abandon their troubled children to the hospital system. Diane Die Despres (Anne Dorval), a feisty single mother, has to pick up her teenage son Steve (Antoine-Olivier Pilon) from the institution where he lives, because he’s hurt a smaller boy. Steve, who has ADHD, is wild, yet charismatic. While she struggles to make ends meet and raise Steve with values, they meet Kyla, a mysterious neighbour who has trouble speaking after a traumatic incident. She’s a former teacher and when Die asks for her help, she reluctantly agrees to homeschool Steve. Even so, Die has trouble with Steve, who has bouts of violent rage and she finally has to decide if she can continue to cope with him at home.
