After suffering a traumatic head injury while playing softball, 14-year-old Deidre “Dee-Dee” Olsen is alarmed and confused when she sees unfamiliar people that no one else can see and initially dismisses her condition as a side effect of her injury.

But when she sees and communicates with her deceased father, Dee-Dee realizes that the people she is seeing are the spirits of the departed. Coming to terms with her newly acquired abilities, she feels confident that she is meant to use her gifts to help and comfort the grieving by delivering messages of hope to the loved ones they left behind.

Everything seems to be going smoothly until the Homecoming Queen, Stacy Amberville, suddenly vanishes without a trace, and the case is classified as a missing person. However, Dee-Dee knows she hasn’t simply disappeared, but has been murdered.

By communicating with Stacy’s spirit, Dee-Dee is also aware of who the killer is, but how can she tell the police chief, Jerome Simms, what she knows without disclosing the secret that she has vowed to keep silent about, without risking her reputation and her own safety?

Because, the murderer knows Dee-Dee is aware of his secret, and when he begins to stalk and threaten her, Dee-Dee must get Chief Simms to believe her before she becomes the killer’s next victim.
