In 1721, the Regent of France proposes a marriage between 11-year-old Louis XV, heir to the French throne, and 4-year-old Maria Anna Victoria, daughter of the King of Spain. The Regent also offers his 12-year-old daughter as a bride for the 14-year-old heir apparent to the Spanish throne. Madrid responds enthusiastically to both proposals, and the ceremonies are promptly organized. The young royals soon find themselves caught in a web of political intrigue.
The Royal Exchange, based on the best-selling historical novel by Chantal Thomas, is a stunning costume drama.
