Denis is a loving albeit overworked father. He struggles to raise his boisterous daughters Janis (13) and Mercredi (9) on his own while holding down two jobs. Everything goes sour when Denis forgets Mercredi one too many times at the school gates. Séverine, a cheerful social worker, is appointed to scrutinize the family’s daily lives and soon cannot avoid condemning Denis to a «parent» training course… Will the somewhat eccentric family be able to conform and remain together under one roof?
