July 1789. At the dawn of the French Revolution, as turmoil brews in Paris, Versailles carries on, careless and unworried, as if isolated from the rest of the world.

Sidonie Laborde, the Queen's young reader, carefree and entirely devoted, takes full advantage of the intimate moments which tie her to Marie-Antoinette, whom she admires so much. Sidonie is unaware that she is about to live out the last three days she will ever have at her mistress' side, in the Versailles of pomp, extravagance, games of leisure and luxury.
