Fabienne and Renaud Lepic decided to break tradition this year. They won't celebrate Christmas with their children. Instead, they're off to Las Vegas to see Céline Dion. Meanwhile, Valérie and Denis Bouley want to impose a sober, eco-friendly, and altruistic Christmas on their offspring. But a revolt's brewing amongst the "Boulpic" children, who demand that their parents give them a good old-fashioned Christmas, complete with Santa Claus, a mountain of presents and a hearty feast. This year, everyone asks the same question: Will there be a Christmas during Christmas? Some flashing lights sequences or patterns may affect photosensitive viewers.
