When Joseph Weissmann divorced his wife Betty, he was 78 years old and she was 75. The Weissmann sisters, Miranda, a successful literary agent, and Annie, a library director, unexpectedly find themselves the middle-aged products of a broken home. Dumped by her husband of nearly 50 years and exiled from their elegant New York apartment, Betty moves to a small, run-down Westport beach cottage. Joining her are Miranda and Annie, who comes along to keep an eye on her capricious mother and sister. As the sisters mingle with the suburban aristocracy, they find themselves struggling with the duelling demands of reason and romance.
