Jeff investigates the disappearance of a wealthy young heiress's aunt. When she is then killed by a hit and run driver he is led to a medium previously visited by the aunt and uses Jeannie as a decoy to foil a thieving operation in which middle class men rob wealthy widows by murdering them in the room of the episode title, which then transpires to be a gas chamber in disguise.
In the pilot episode Marty Hopkirk is murdered by the husband of a client but returns as a ghost to help Jeff bring the man responsible for his murder to justice.
Concerned for Jeff's mental health Jeannie sends Jeff to Dr. Conrad at the Lambert Clinic where it turns out he is the mastermind of a series of robberies of his patients using hypnotic suggestion, forcing Marty to try to find a way to break Jeff from his control before Jeff has been so severely hypnotized that he loses the ability to see Marty. David Bauer stars.
