Crustacés et coquillages

Marc decides to take his wife, Béatrix, and their two teenagers, Laura and Charly, to a house in the country where he spent his childhood vacations. Laura, 19, falls in love with a biker while his son, Charly, 17, hangs out on the beach with Martin, who’s secretly in love with him. Béatrix begins to believe Charly is gay, which upsets Marc. Meanwhile, Béatrix’s lover, Mathieu shows up to convince her to leave her husband once and for all, while Marc, partly thanks to the nighttime escapades of Charly and Martin, bumps into an old flame from his youth.
