The wealthy American Penny (Kathryn Leigh Scott) moves to the lonely house of her boyfriend Harry (Simon MacCorkindale) in the countryside of England to recover from a recently mental illness. While sleeping alone during the night, Harry's friend Charles (Stanley Lebor) breaks in the house to rape Penny and she shots him in the face in self-defense using Harry's shotgun and faints. When Harry returns home, he convinces Penny to hide the body in a grave in the woods. But soon Penny starts to see Charles everywhere and Harry's friend Margaret (Mia Nadasi), who is a medium, proposes a séance to get rid of the spirit of Charles. But she concludes he is a strong spirit seeking revenge and they need a most powerful psychic to control him.
"Visitor from the Grave" is a predictable episode from "Hammer House of Horror" that never convinces the viewer. The surprising plot point is only in the very ending. Unfortunately the DVD Box released in Brazil by the shameful "Vinyx Multimedia" distributor with the "Hammer House of Horror" collection (called "A Casa do Terror" in Portuguese) has problems specially on the DVD number four that stops from the twist of this episode on and it is not possible to see the conclusion of this episode and the next two episodes ("The Two Faces of Evil" (12) and "The Mark of Satan" (13)). My vote is five.
Title (Brazil): "Visitante do Túmulo" ("Visitor from the Grave")
