Beyond Reality: The Burning Judge (1992)
Roxanne, a fraudulent “psychic and reader” has a nightmare of being burned at the stake by a grim 17th Century zealot. Then she awakens to find the same man nosing around her shop and accusing her of being a witch. Laura and J.J. discover that both Roxanne and the man are reincarnated from 300 years ago, at which time the man – Jebadiah Smith – had had sex with her, then felt so guilty he killed her in a witch-hunt. When the present-day Jebadiah kidnaps Roxanne and Laura in order to burn them both, they confront Jebadiah with this knowledge, causing Jebadiah to spontaneously combust in shame and horror before he’s able to repeat the original sin.
