Joy Hockstatter has been trying to help her dad, Bob, hold the family together since her Mother's death. Although only 15, Joy has tried to become a kind of surrogate Mom to her older and younger brothers. Every day she looks across the street, idolizing the 'perfect' Wellman family. After a freak accident, involving some suspicious cards, Joy wakes up as one of the Wellmans with a new mother, father and older sister. Her new life initially seems to have changed for the better, only now Bob and her brothers have taken a huge turn for the worse and the only one who recognizes Joy from her previous life is her old dog, Levi.
