An art history professor, Suzanne Nelson escapes her failing marriage by retreating into her research and the fertile world of her imagination. La Tour's ability to create luminous portraits of peasants stood in sharp contrast to his aggression toward the poor, but little information about his life exists, and Suzanne finds herself filling in the details, trying to understand how a man capable of brutality could create such beauty. Unwittingly looking to her own life and marriage, she invents La Tour's final painting sessions with a young model, a village girl. When the girl modestly disrobes for the artist, he discovers a marking on her back that she is obviously unaware of. By painting her, La Tour in effect reveals to the girl exactly who she is and who she is not. Her reaction is at once astonishing and utterly warranted. In Suzanne's mind, this encounter becomes a story of truth and lies, art and identity.
