Fanny is soon possessed of beauty as well as a keen mind and comes to the attention of a neighbor, Henry Crawford. Thomas promotes this match, but to his displeasure, Fanny has a mind of her own, asking Henry to prove himself worthy. As Edmund courts Henry's sister and as light shines on the link between Thomas's fortunes and New World slavery, Fanny must assess Henry's character and assert her heart as well as her wit.
