Paul is a gentle, childlike man who has been nurtured—and overprotected—by his two quirky aunts in Paris ever since he lost his parents as a young child. Now at the age of thirty-three, he still hasn’t spoken a word. However, he communicates his personality through vibrant suits that could rival any character from a Wes Anderson film in terms of nerdy style. Paul’s aunts have a singular ambition for him: to see him triumph in piano competitions. Despite his diligent practice, Paul feels unfulfilled until he encounters the influence of his upstairs neighbor. Appropriately named after the famous writer, Madame Proust provides Paul with a special brew that helps him recover suppressed childhood memories and sparks the most enchanting fantasies.
