Two Original Screenplays of the Supernatural by Michael B. Druxman BLACK WATCH: A group of mercenaries, bent on ransoming both Edinburgh Castle and its Crown Jewels, seize the fortress. Their plan is foolproof, ingenious, but what they don't count on is the interference of a retired Army sergeant, now a tour guide, a young soldier, and the ghosts of the castle, who, once released, roam about seeking a bloody revenge for past injustices. THE CAVERN: Following an earthquake, tourists have begun to disappear in the Lorenzo Caverns. The FBI claims that a bear is the culprit, but the local sheriff and an esteemed archeologist suspect that the missing people have become the victims of a bloodthirsty alien creature.
