The Affair of the Necklace (2001)

Centuries ahead of her time, Jeanne de la Motte-Valois was a beguiling, unconventional woman who broke all the rules and masterminded an ingenious and perilous conspiracy that scandalously incriminated the rich and famous; it may well have paved the way to the guillotine for Queen Marie Antoinette and King Louis XVI--dismantling 800 years of absolute monarchy. Set in the waning years of the 18th century, the tale, based on true events, centers on Jeanne and her quest to recover what was so unjustly taken from her. Aristocrat Jeanne is tragically orphaned by her parents, direct descendents of Henry II. Her only inheritance is a tattered genealogical chart proving her noble origins. Jeanne's passionate life mission becomes taking her rightful place at the Royal Court. During her quest, she discovers that her family was torn apart by the treacherously fickle, royal politics preceding the French Revolution. To avenge her family, she fixates upon stealing a spectacular 2,8000 carat diamond necklace.
