A psychologist's 10-year-old patient claims she's being menaced by unseen forces after her parents were killed in a car accident. What's more bizarre? The psychologist has seen these symptoms before, in a former patient who mysteriously disappeared. And the shrink worries that if she can't unravel the workings of the 10-year-old's psyche (and soon!), this little girl is destined for the same unknown fate.
