Dahlia Ashwell was Britain's youngest serial killer before she was caught and admitted to a psychiatric hospital under the care of Dr McGuire, who cares more about writing a book and making a profit off of her crimes.
Dubbed by the media as the BONETAKER, Dahlia finds amusement in messing around with Dr McGuire but eventually gives in and agrees to a series of interviews for his book.
Dr McGuire thinks he's going to write a best seller, and is so busy concentrating on writing it that he doesn't realise what's going on in his own hospital.
