As Halloween approaches, a tough-minded, high-priced defense attorney becomes the target of a supernatural stalking. A former client of hers, a demon-worshipping psychopath who feels she has betrayed him, begins evoking ghosts and other such disturbances to hound her day and night. Though confined to a death row prison cell, he promises a painful death on Halloween night. Janine regards the holiday and indeed all of the occult as "kid stuff," but she's never been one to back away from a fight. She does her own research into demons, looking for ways to stop the madman. On Halloween night, with her house surrounded by jack-o'-lanterns and other magical wards, Janine conducts a demon summoning of her own, but must strike a dreadful bargain with it in order to escape.
