The Enguerrands are getting ready to spend another summer in their family house deep in the verdant Provencale countryside. With Frédéric and his wife, Frédérique, are their son, cousins, Grandma, sister, brother-in-law... the whole clan. Hugo has recently moved in next door. A solitary man, he views the world through keen and curious eyes. Invited by Frédéric to a family barbecue, an amused Hugo openly parades his homosexuality. After a convivial dinner, the two men stay up on the terrace till dawn, exchanging their radically different visions of love. Entirely unaware of the intimacy of their exchange - and despite the seeming normality of the holiday - Frédérique nonetheless notices a distance opening up between her and her husband, and a powerful bond of love developing between Frédéric and Hugo, a bond which grows stronger daily. Turmoil takes possession of each of them, spreading confusion in every heart.
