A ghostly knight is making a habit out of executing certain persons responsible for the 'desecration' of his burial site; that is, anybody involved with the creation of a restaurant/disco near the knight's resting place. Kolchak catches on when he happens to be in the wrong place at the wrong time and witnesses one of the murders with his own eyes. An axe that's been blessed is the only thing that will stop the ghost from exacting his gruesome revenge.
