Pierre is CEO van een grote familieonderneming. Hij staat op het punt de deal van de eeuw te sluiten. Hij moet enkel nog een formaliteit afhandelen: de handtekening van zijn neef Adrien, die 50% van het bedrijf bezit. Deze idealistische dromer, die de blunders opstapelt, is zo blij Pierre te zien dat hij tijd met hem wil doorbrengen en de ondertekening wil uitstellen.
