Dead Man's Gun - Season 1 Episode 15 The Mesmerizer

without acknowledgement to Edgar Allen Poe's ""The Facts In The Case of M. Valdemar"", this bizarre tale is of a womanizing hypnotist who falls for the wife of a dying millionare. She persuades the hypnotist to use his talent to ease her husband's suffering. But as hubby sinks deeper and deeper into death, the hypnotist sees an opportunity to achieve fame by keeping conssciousness and motor nerves alive in a corpse, at the same time arresting decay, and creating an immortal dead man! Only after the wife finds out that she can't inherit anything as long as her husband is still considered alive, and the hypnotist finds out he can't remove the hypnotic state do things start to literally fall apart! The twist ending is particularly gruesome and ironically fitting
