What is the plot of Persuasion by Jane Austen?

Persuasion, published in 1817, is romantic novel with themes of mature love, second chances, and family loyalty.

Persuasion centers around Anne Elliot, who is one of three daughters of Sir Walter Elliot.  Sir Walter is a widower who is conceited and selfish, and spends lavishly and beyond his means, which has forced the family to retrench by renting out their landed estate and relocating to lower-cost Bath.  

Anne is wise and kind but, at 26, is past her prime.  At 19, Anne fell in love with, and accepted a marriage proposal from, Frederick Wentworth, a promising naval commander who is of a lower social status than Anne.  Anne is persuaded by her family (father and older sister) and close friend (Lady Russell) to break off the proposal.  

The novel starts with the family planning for their relocation to Bath, and the Elliots have coincidentally rented their home to the sister and brother-in-law of Frederick Wentworth, now a naval captain.  This provides Captain Wentworth with the opportunity to re-enter Anne’s life and her social circle.  Captain Wentworth has achieved much success and wealth from his naval career.  While Anne immediately notices and admires Captain Wentworth, he initially remains cold to her and commented that she has aged significantly since he last saw her.  The plot takes various twists and turns, with other potential romantic interests for Captain Wentworth and Anne. As Captain Wentworth sees more of Anne, he learns to appreciate and respect her, and ultimately they fall in love again and agree to renew their engagement.
