Annie Mackenzie is just an ordinary girl, or at least that's what she thinks. On her way home from a party late one night, she realizes she's being followed by a mysterious figure. By the time the night is over, Annie's life seems to have been changed forever. Or has a long-buried secret simply caught up with her? At the edge of Middlewych, a secret testing facility hides a series of shocking experiments. For centuries, humanity has been fascinated by tales of vampires, werewolves and witches. Now one scientist believes he has found a way to reverse-engineer these creatures, creating an army of nightmares. Some of these experiments, however, are none too pleased by their treatment. And one of them in particular has a plan for revenge.
