When a young girl begins hearing voices, she hires the "GhostWatcher," Laura Kove, to investigate who the voices belong to and what they want.

Laura Kove is an agoraphobic young woman whose world turns upside down when she discovers that the apartment she's locked herself into is haunted. Turning to the internet for help, she enlists the aid of Elizabeth Dean, a scam artist who passes herself off as a ghost hunter. At first, Elizabeth doesn't buy Laura's story but she soon becomes a true believer.
