A pleasurable comedy of love and sexual identity unfurls over a balmy summer holiday. Marc (Gilbert Melki) takes his wife Béatrix (Valeria Bruni Tedeschi) and their two children to the seaside house of his youth. The Mediterranean wind blows and the heat of summer strokes their passions and desires. Nineteen-year-old daughter Laura, has a rendez-vous with her biker boyfriend and then heads off to Spain, while their son Charly, 17, roams with his best friend Martin. Béatrix is sensitive to the erotically charged atmosphere that exists between the boys, and imagines that her son is gay. Marc meanwhile is upset at the prospect of it, although Béatrix is determined to be open. When Béatrix's lover Mathieu shows up, and Marc's old flame appears, complications ensue and chaos develops.
