In a time now lost in the mists of memory, the great King Arthur rules in the legendary citadel that is Camelot. His Knights of the Round Table commit acts of derring-do and spend their spare time jousting, much to the delight of the local citizens and especially to Princess Ilene, a guest at Camelot. Watching her from afar is a young, inexperienced squire called Valiant, and when the young Welsh princess is sent home to marry Prince Arn, Valiant contrives to accompany her masquerading as Sir Gawain.
