Lizzie

A clerk at a museum, twenty-five year old proverbial "plain Jane" Elizabeth Richmond is a bundle of nerves and neuroses, as such she not having much of a social life or friends, despite the efforts of museum colleague, Ruth Seaton. Her maternal aunt, Morgan James, with who she has lived most of her life, doesn't help matters as she views Elizabeth as a problem, the result of Elizabeth's mother/her sister, largely absent, being a tart and a drunk when she was alive. Frequently coming down with ailments, especially headaches, without explanation, Elizabeth has only become more nervous in receiving threatening notes left in her purse by someone named Lizzie, who she doesn't know. Despite Morgan not believing in such, their neighbor Walter Brenner convinces her to send Elizabeth to a psychiatrist he knows, Dr. Neal Wright. Placing Elizabeth under hypnosis with her consent, Dr. Wright discovers that she suffers from dissociative identity disorder, two distinct personalities beyond Elizabeth ultimately showing their selves: the aforementioned Lizzie, the all-knowing one who is a mirror image of Elizabeth's mother in being a brazen tart; and well-adjusted Beth, who has largely been quietly hiding until feeling the need to come forward. Needing the cooperation of Aunt Morgan, which may be difficult to get in she treating what Elizabeth is going through as one big game, Dr. Wright has to discover the cause of Elizabeth's disorder to be able to treat it, hopefully with the end goal to nurture the most well-adjusted part of Elizabeth - namely Beth - to the forefront.
