In this tongue-in-cheek take on classic themes in children's literature, the four Willoughby children set about to become "deserving orphans" after their neglectful parents embark on a treacherous around-the-world adventure, leaving them in the care of an odious nanny.
Thirty years after their disappearance, the previously frozen Willoughbys have thawed out and returned from the Alps, to the consternation of their children and grandchildren.
