One afternoon in Saint-Germain-des-Prés, 18-year-old Philippe meets 16-year-old Frédéric. Their eyes meet, they talk and decide to spend a sensemble weekend in Deauville. But it's not that easy to get to know each other. From surprises to concessions, this weekend teaches them how difficult it is to understand each other and not waste the pleasures that come our way; and that sometimes, at the end of the day, we'd like to do the trip all over again, in reverse.
