Madison is an American film star: she is beautiful and talented and her French accent may be impeccable but she is secretly ashamed of her bourgeois Texan roots. Her husband Olivier, is the darling of the sophisticated Left Bank: philosopher, gourmand and media personality, he craves adoration. Olivier and Madison indulge in fine wines, bon mots, and some execptional cheeses. Everything seems perfect right up until the moment a new English nanny, Anna, appears at the imposing doors of their Rue du Bac apartment. Gamine and artless, Anna unwittingly sets in motion a chain of events that will gravely endanger the Malin's daughter and their charmed lives.
