Part-time ghost tour guide Savannah's life took a turn when her best friend, Shane, unexpectedly died. When Shane's enigmatic twin brother, Cory, transferred to her school and started showing up everywhere she went, she thought her life couldn't get any worse; it was like being haunted.

Then, her doorbell started ringing - randomly. Even after she disconnected it. With a growing sense of dread, Savannah suspects that she's going through what every ghost enthusiast who ever went on her tour hoped to experience; she started to think, just maybe, she really was being haunted.
