Swashbuckling sword and sorcery adventure with Joanna Lumley as an evil witch who orders a marauding bunch of Vikings to dig up Merlin's grave to steal his book of spells. Now, if she can get her hands on the magical sword Excalibur, there will be nothing to stop her reigning supreme over Camelot. Meanwhile, the knights of Camelot are jousting for the hand of Princess Ilene, and a young unknown squire, Valiant, is commanded by King Arthur to escort her to safety. Great for youngsters who like something a bit meatier than the usual kids' stuff.
