Michel en Claire zijn met hun drie veeleisende dochters op weg naar hun vakantiehuisje. Het huisje is verwaarloosd en het opknappen ervan zal hun gehele vakantie opslokken. Bij een tankstation ontmoet Michel een oude klasgenoot, Harry, die hij zich niet meer kan herinneren. Na lang aandringen 'herkent' hij deze Harry. Deze twintig jaar vergeten vriend nodigt zichzelf en zijn vriendin meteen uit voor een gezamenlijke vakantie. Harry dringt steeds verder door in het leven van Michel en laat hem naar zijn pijpen dansen.
Nee, helaas is Harry, un ami qui vous veut du bien nog niet beschikbaar op Netflix in Nederland.
