Back in the days when everyone believed in magic, a horrifying fire-breathing dragon terrorized the sixth-century British countryside. The only hope for the beleaguered citizens is an aging sorcerer (Sir Ralph Richardson). But when he is killed before he can save the people, the task falls on his young apprentice, Galen (Peter MacNicol). Galen's mission is complicated by resistance from the king - and by falling in love - but his biggest challenge comes when he is suddenly face to face with the dreaded monster. Is his magic enough to save him?

A travelling troupe of jousters and performers are slowly cracking under the pressure of hick cops, financial troubles and their failure to live up to their own ideals. The group's leader, King Billy, is increasingly unable to maintain his warrior's rule while the Black Knight is being tempted away to LA and stardom, as they all have to ask why they were here in the first place.
