In a left-leaning, working-class community in the east of France, a father raises his two sons alone. After the death of their mother, his bond with Fus, his eldest, and Gillou, the youngest, is a close one.But everything changes when it becomes clear that Fus - contrary to his socialist upbringing - has begun associating the local far-right political group. Hanging out with others youths, distributing leaflets for Le Pen's National Front, it's not long before activities which might on the surface appear harmless lead to violent confrontation.How can a father and a son find common ground when everything seems set to break them apart? A sudden tragedy will force them to find an answer.Short, sharp and ultimately heartbreaking, Laurent Petitmangin's What You Need from the Night shines a spotlight on lives that are unfolding in forgotten corners of the country, and how the far right lures in young people just looking for camaraderie - with devastating consequences.
