The competition title earned the Jury Prize in Cannes, with Dolan sharing the honor with French filmmaker Jean-Luc Godard. Seville International sold the Canadian film, which stars Anne Dorval, Antoine Olivier Pilon and Suzanne Clément. Set in a fictional Canada, where a new law allows distressed parents to abandon troubled children to the hospital system, a feisty widow tries to cope with Steve, her wild yet charming ADHD son.
