The four Grace sisters - Liz, Sal, Tilly and Addie - love their quiet country life. To some, their insular world might seem dull, but the sisters and their father, Mr. Grace, truly are the happiest of families. That is, until Aunt Rona comes to town. Rona intends to stay indefinitely, and her superior, meddlesome attitude immediately sets the sisters' teeth on edge. Throw in another unexpected houseguest, some potential suitors, and a case of mistaken intentions, and the members of the Grace family suddenly find themselves quite out of their element. Can they make it through the summer and return to their quiet ways? Or will their close-knit family change forever?.
