Charles (Jean-Pierre Darroussin), a successful lawyer from a wealthy Parisian family, turns his back on his life of privilege. He divorces his socialite wife (Anne Canovas), moves into a modest apartment building, takes up riding a bike, throws away his phone and transitions into legal aid work. His quest for moral decency is misunderstood and manipulated in turn, and Charles soon finds himself looking after the teenaged next-door neighbor and her cynical nanny (Valérie Stroh).
