Henry Dashwood, his second wife, and their three daughters live for many years with Henry's wealthy bachelor uncle at Norland Park, a large country estate in Sussex. That uncle decides, in late life, to will the use and income only of his property first to Henry, then to Henry's first son (by his first marriage) John Dashwood, so that the property should pass intact to John's four-year-old son Harry. The uncle dies, but Henry lives just a year after that and he is unable in such short time to save enough money for his wife Mrs Dashwood, and their daughters, Elinor, Marianne, and Margaret, who are left only a small income. On his deathbed, Mr Henry Dashwood extracts a promise from his son John to take care of his half-sisters. But before Henry is long in the grave, John's greedy wife, Fanny, persuades her husband to renege on the promise, appealing to his concerns about diminishing his own son Harry's inheritance, despite the fact that John is already independently wealthy thanks to both his inheritance from his mother, and his wife's dowry. Henry Dashwood's love for his second family is also used by Fanny to arouse her husband's jealousy, and persuade him not to help his sisters financially.
