She is a pianist, he wants his peace. Both have recently become neighbors, and the wall between their apartments is so thin that every noise can be heard. When the wallflower Madame moves into her new apartment, it is clear to the oddball game inventor Monsieur: the noisy neighbor must be driven out by all means. However, she resists fiercely, and the singles loudly make each other's lives hell. But soon the two realize that they have a lot in common. Without ever having seen each other, a blind date through the wall begins... In this refreshing comedy hit from France, Mélanie Bernier (MADEMOISELLE POPULAIRE) and Clovis Cornillac (ASTERIX AT THE OLYMPIC GAMES) shine as quarrelsome neighbors whose attraction brings down every brick wall.
