Isabel Walker is a twenty-something American film-school dropout who decides to visit her step-sister Roxanne, a poet who now lives in France.

To her surprise Roxanne learns that a painting of Saint Ursula that was gifted her from the Walker side of the family might be worth several thousand dollars.

In the meantime, Isabel begins an affair with Edgar, a septuagenarian who is Claude-Henri's uncle, after he gives her a Kelly bag and proposes she becomes his mistress.

As the Walkers continue to try to block the sale of the painting, they meet with an auctioneer from Christie's and learn that it is likely an original Georges de La Tour and is worth about a million dollars.

Isabel returns home to Roxanne's and discovers that Tellman killed Charles-Henri and attempted to murder his wife, Magda.

At Charles-Henri's funeral, Isabel reflects that Roxanne always gets what she wants and will now be treated as a valued member of the Persand family without the stain of divorce upon her.
