Laponie avec François-Xavier Demaison et Ophélia Kolb

After years without seeing each other, two sisters (Ophélia Kolb and Élisa Erka) and their husbands (François-Xavier Demaison and Patrick Mille) reunite to celebrate New Year's Eve together in Santa's homeland. But when one's daughter tells the other's son that Santa Claus doesn't exist, the evening descends into chaos.

So begins a showdown in ugly Christmas jumpers and woollen socks.
