Abby hasn't sleepwalked in years, but the death of her mother sparks a relapse. It isn't long before she wakes up in an unimaginable nightmare, slumped over the steering wheel of her car with a motorcycle overturned nearby.

She begins to receive mysterious phone calls and threatening notes, warning her not to tell anyone the truth about the crash.

She turns to the local psychiatrist, Dr. Jason Coble, for advice, and they find comfort in one another's arms. However, whoever is connected to the crash will not stop until they are certain their secret is safe, and Abby soon realizes that she can trust no one until she finds out what happened that horrible night.
