Mrs. Dashwood and her daughters Elinor, Marianne, and Margaret, become impoverished after the death of her husband. His farm, Norland in Sussex, must pass to John Dashwood, son of his first marriage. Although John promised his father to take care of his stepmother and sisters, his egotistical wife, Fanny, easily dissuades him from giving them part of his inheritance. The Dashwoods are treated as unwanted guests in their own home, and soon begin to look for another place to live.
Mrs. Dashwood and her daughters soon march from Norland to Barton Cottage in Devonshire. His landlord is Sir John Middleton, a distant cousin who generously offers them a low rent. He lives in Barton Park with his wife, cold and elegant, and her children.
