Theatre Macabre (1971)

S1E12 Markheim

On Christmas Day, a man kills an antique dealer to rob him, but soon finds his guilt taking on a terrifying form. A mysterious stranger—possibly the Devil himself—appears to haunt him, forcing him to face the weight of his crime. Tormented by his own conscience made flesh, he must decide between continuing down a path of darkness or surrendering to the truth. In the end, he chooses confession, breaking free from sin before it consumes him entirely.
