Dinah's father is headhunted for a new job at the Biogenetic Research Centre, but the Demon Headmaster is the director. This time his lust for power sees him meddling with evolution itself; the Headmaster has created an Evolution Accelerator, a machine to speed up the evolution process. For this he wants Dinah's DNA to create a "perfect" human, with Dinah's intellect but no emotions. He then puts Dinah into terrible danger to test his theories.
