The year is 1976, and the family, Frank McKotch, an eminent scientist; his pedigreed wife, Paulette; and their three beautiful children has embarked on its annual vacation at the Captain's House, the grand old family retreat on Cape Cod. One day on the beach, Frank is struck by an image he cannot forget: his thirteen-year-old daughter, Gwen, strangely infantile in her child-sized bikini, standing a full head shorter than her younger cousin Charlotte. At that moment he knows a truth that he can never again unknown something is terribly wrong with his only daughter. The McKotch family will never be the same. Twenty years after Gwen's diagnosis with Turner's syndrome, a genetic condition that has prevented her from maturing, trapping her forever in the body of a child, all five family members are still dealing with the fallout.
