A rich, nasty boss sends the nicest family in the world on holiday to the Hell-themed Underworld: The Theme Park.

The richest, nastiest man in the world isn't happy. He made billions by persuading the world that Bad is Good, but it wasn't enough. He needed a challenge. So he bought Basingstoke and turned it into Underworld - The Theme Park. It didn't take much work. But it still wasn't enough. So he brought the Baskervilles, the nicest family in the world: if he could turn them bad, then he'd be happy. Boy was he in trouble!—Anonymous

British family Baskerville decides to move from their nice hometown and move to Underworld the Theme park owned by The Boss, where bad is good and good is bad. Only 10 year old April Baskerville knows that she and her family will never return to their old town. Their new neighbors include Vampires, Frankenstein, Zombies, and mummies. Just the run of the mill hell.—Twisted Kitten
