Based on the best-selling novel by Chantal Thomas, Léa Seydoux stars as one of Marie Antoinette's (Diane Kruger) ladies-in-waiting, seemingly an innocent but quietly working her way into her mistress s special favors, until history tosses her fate onto a decidedly different path. With the action moving effortlessly from the gilded drawing rooms of the nobles to the back quarters of those who serve them, this is a period film at once accurate and sumptuous in its visual details and modern in its emotions.
