The Great War is over but for Edith Potter an equally devastating conflict is about to begin. She is unhinged by a secret so terrible her conscious mind doesn't acknowledge it. It is 1927 and Dr Stephen Maynard is using the new science of psychoanalysis to restore her sanity. From his first meeting with her in the lunatic asylum, Dr Stephen Maynard is determined to bring her back to reality. During the long challenge, her disturbed behaviour forces him to confront his limitations – already severely stretched by the presence of someone prepared to use whatever weapons they can to ensure she maintains her silence.
