Enter the world of Olivier and Madison Malin, glittering inhabitants of Paris's exclusive Left Bank. The Malins' life together with their daughter is the stuff of dreams - and carefully-selected celebrity magazines. Madison is a film star: her beauty, talent and perfect accent hiding her Texan roots, and the fact she's just turned forty. Her husband, Olivier, is the darling of the sophisticated Left Bank: philosopher and media personality, he craves adoration (and is a little too willing to return it). Everything seems perfect - if a touch pretentious - until the moment new English nanny, Anna, appears at the doors of their Rue du Bac apartment. Anna unwittingly sets in motion a chain of events that will endanger their charmed lives - in ways no-one could have foreseen.
