The Frosts are a typical American family. Barb and John, married almost fifty years, are testy and bored with each other . . . who could blame them after all this time? At least they have their daughters -- Barb's favorite, the perfect, brilliant Juliet; and John's darling, the free-spirited Sadie. The girls themselves couldn't be more different, but at least they got along, more or less. It was fine. It was enough. Until the day John had a stroke, and their house of cards came tumbling down.
