Paul (
Guillaume Gouix), a young virtuoso pianist and a fan of chouquettes, lives with his two aristocratic aunts, Annie (
Bernadette Lafont) and Anna (
Hélène Vincent), who run a dance class of which he is the official pianist. He has been mute since the age of two, when he saw his parents, Anita and Marcel, die in front of him. One day, he brings a record to Mr. Coelho (
Luis Rego), the blind piano tuner who dropped it down the stairs, and finds it in the home of Mrs. Proust (
Anne Le Ny), a neighbor who grows vegetables at home and plays the ukulele. In secret from his aunts, he undertakes therapy with Mrs. Proust which consists of strange herbal teas whose taste is masked by madeleines and which make him relive in flashes of memory the events which led to the tragedy. In turn, Paul learns to manage his relationships with music and with Michelle (
Kea Kaing), a young Chinese cellist and adopted daughter of a friend of his aunts.
