In London, Willoughby acknowledges no connection to Marianne and marries wealthy heiress Grey. Elinor must hide her heartbreak when she learns Edward Ferrars is engaged to Miss Lucy Steel; when his mother learns of the engagement she disinherits him. Fortune smiles unexpectedly on both Dashwood sisters.
