Felix Milne (Brugess Meredith) is a practicing psychotherapist which is a budding profession in 1940's London. Although he is not an accredited doctor, he enjoys a position at a local clinic as well as a fairly lucrative private practice. Lately he has become bored with the same whiny rich old lady stories and he longs for something different to happen. He is hoping for a patient that he can really help.
Boredom in his home life is another problem. The romance has gone out of his marriage and he feels he is no longer attracted to his wife, Patricia (Dulcie Gray). In his eyes, she is clumsy, cowering, stupid and lacking is social skills. He is again longing for something different to stir up his love life.
He doesn't have long to wait for change when Sweet Molly Lucian (Barbara White) pays him a visit. She is concerned for her husband Adam (Kieron Moore). Adam has attacked her while she was sleeping and he doesn't remember a thing. She thinks it may have something to do with him being a prisoner of war in Japan but she cannot be sure. Felix is reluctant to take the case as he believes this may be a little more than he can handle. Molly presses saying Adam will never see a doctor and they don't have very much money for treatment. Felix's sympathies (and curiosities) get to him and he finally agrees to set up an initial consultation.
Patricia is very concerned with the prospect of this new patient. She and Felix discuss it briefly as they prepare for a dinner party with Peter and Barbara Edge (Michael Shepley and Christine Norden). Conversation quickly turns from the patient to Barbara. It's obvious that Patricia is more concerned about "Babs" than Lucian. She senses a little too much interest from Felix and a mutual danger from Barbara. This is apparent at the dinner party and proves to be a worthy suspicion later on.
The next afternoon drags on but Felix finally comes to his last appointment for the day. It is Adam Lucian. A very reluctant Adam Lucian and probably for good cause. As Felix waits he notices a man with a limp pacing back and forth outside. The man finally enters the house and it is announced that Mr. Lucian is present. Adam is at first skeptical but begins to loosen up a bit with conversation. The meeting goes fairly well and he agrees to see the psychotherapist again. Felix has grave concerns because he believes he sees an acute case of schizophrenia. After many sessions he still cannot get through to Adam. Felix is becoming more and more unsure as to how serious this case is so he consults a doctor friend. The doctor recommends injecting Adam Lucian with truth serum to release the memory blockage which is hindering progress.
In the next session Adam agrees and the serum is injected. Felix pries into Adams mind to find the root of the illness. He gathers the story of Adam's torture and escape as a POW. But in the process, Felix sees something much more. The roots lie in Adam's childhood and a fear of the darkness. When the session is over, Felix's concern has turned to fear. He fears for Molly Lucian's safety. This prompts him to call the Molly in to recommend she leave her husband or try to place him in a hospital. She refuses to do both as she is afraid it will harm her husbands mentality even more. Never the less, Felix warns her not to be too far away from Adam in the dark. She is not to ever let him see her as a shadow or no one can say what might happen. Molly agrees but carelessly forgets one evening as she enjoys the moon from the balcony.
