 The Wilkinson family become ghosts after they die in a tragic bombing in World War II, apart from Trixie - Mrs. Wilkinson's sister.Initially, they haunt their home, Resthaven, and they adopt another young ghost, a girl they name Adopta, who has no memory of her past.When the arrival of new owners forces them to leave, they travel to London and reluctantly begin haunting an underwear store, and apply to the Dial-a-Ghost agency for a new home.
