Female doctor Valerie is asked to see a mysterious patient named Aveling. When the young woman is first brought into her office, Aveling is bedraggled and wild. The guards warn Valerie to be cautious as Aveling has a tendency to run. Yet, Valerie is given no information about the girl, and the girl refuses to speak. As time passes, a tape recorder becomes the doctor-patient connection as Aveling tells her story. Valerie knows Aveling has suffered some kind of trauma in her recent past that caused memory loss, and the more Valerie learns, the more horrified she becomes. How could someone hurt Aveling? She seems like an angel-although even the devil was an angel once.
