After Antoine was fired from his job, he became a stay-at-home dad taking care of his four children, while his wife Isabelle restarts her career as a lawyer. For Antoine, the family's upcoming ski vacation is a godsend: he can finally take a break from parenthood and enjoy a luxury ski resort! But just as they are about to step on the train, Isabelle is called back to work for an emergency and Antoine has to deal, on his own, with his four mischievous kids going wild on the slopes and in the fancy hotel, as the trip turns into total chaos…
Antoine, a history teacher in his early 50s, learns that he has become very hard of hearing. Unable to own up to his handicap, he resigns himself to living in his bubble, even though his entourage finds his behavior increasingly odd. His encounter with Claire, widow and mother of a young girl who has stopped speaking, will lead him to open up to the world.
