synopsis
In the conclusion of the four-part story "Battlefield," the ages-old battle for possession of the Sword Excalibur continues to rage on -- this time with dangerously high-tech weapons -- in the England of the 1990s. According to the scenario at hand, the Doctor (Sylvester McCoy) is Merlin and Ace (Sophie Aldred) is the Lady of the Lake -- but who, pray tell, has been "cast" as King Arthur? This question must be answered before the sorceress Morgaine (Jean Marsh) is able to lay claim to Excalibur by unleashing the dreaded Destroyer of Worlds. Originally telecast on September 27, 1989, "Battlefield, Episode 4" was written by Ben Aaronovitch.
