Despite a traumatic event, a group of friends decide to go ahead with their annual beach vacation. Their relationships, convictions, sense of guilt and friendship are sorely tested. They are finally forced to own up to the little white lies they've been telling each other.
On vacation in the Luberon, a high ranking civil servant, in love with the good old fashioned thinking, has to put up with a bunch of troublemakers in his haven of tranquillity and prevent them from watering in circles. Wife, child and mother-in-law in the front row, brother-in-law and sister-in-law as bonus gifts. Add to that a terrible heat wave and a mother left alone in her apartment in Paris... The cocktail is boiling, even explosive... with this heat it will be hard to keep it cool.
