Benoît Jacquot’s nuanced satire follows businessman Grégoire Jeancourt (Fabrice Luchini) on his return home after a 4-month stint for white-collar crime, which has seemingly transformed him from a captain of industry to an eccentric innocent. His family, including bemused wife Agnès (Isabelle Huppert) and TV host brother (Vincent Lindon), grapple with this striking shift in character.
