A girl, who lives with her deaf parents, discovers that she has the gift of singing.

The Béliers are ordinary people: Rodolphe and Gigi are married, have two children and run their farm for a living. Ordinary people? Well, almost... since three of them, Dad, Mum and their son Quentin, are deaf. Which is not the case of the boy's big sister, Paula. And not only can she speak but her music teacher scouts her beautiful voice as well. He offers her to sit for the entrance exam of the Maîtrise de Radio France, a vocal elite choir in Paris. Her parents, who rely on her as their ears and mouth in the outside world, take the news badly. Paula, who hates the idea of betraying her parents and her brother, goes through a painful dilemma...—Guy Bellinger

The whole Bélier family is deaf, except for 16-year-old Paula, who is her parents' vital translator in their day-to-day life, especially in matters concerning the family farm. When her music teacher discovers that she has a fantastic singing voice, he offers her the opportunity to enter a big Radio France contest, and the entire family's future potentially has big changes in store.
