Now that Hanna has accepted her powers, she and her ghostly best friend Brandon are ready to help another ghost cross over. When a friend at school admits to not being able to sleep well due to some strange wailing she hears at night, Hanna knows this is the job for her.
That same day, Caleb asks Hanna to contact a poltergeist. This job seems daunting as she is barely coming to terms with her powers-not to mention still struggling with regular high school issues and newly separated parents. Yet, after making a deal with the handsome bloodsucker in exchange for a date for Trina and information on the missing psychic, she agrees to try.
Caleb insists that they must hurry or else his vampire queen will go berserk but calming a poltergeist is no easy task. Even with Gran and Brandon's help, Hanna struggles to get the information they need to prevent a vampire street war that will include human casualties, starting with herself and her family.
