Annie Hawthorn's life is a living hell. She's about to graduate from high school, but she's caught the eye of the campus mean girl. Seeking some payback, Annie unleashes a little hell of her own using her late aunt’s grimoire.
Now there's a demon on the loose and things aren't so funny. Annie's best friend has been turned into a cat. She's doing her homework in hell. Her after-school job has frequent demonic interruptions.
But it's worse than that, because Charlie, the demon, claims that her aunt isn't dead. She owes him a debt. And until Annie can find her, he's holding her life ransom.
