This comedy offers yet another sanitized and very loose adaptation of Mark Twain's dark satire A Yankee in King Arthur's Court. This time, the story centers on Calvin Fuller, a nerdy young adolescent living in Reseda. The gangly, unsure youth is first seen standing at bat, ready for yet another strike out. Suddenly a terrible earthquake hits and as the others run for safety, the hapless Calvin is swallowed up in a gaping chasm. He falls and falls until he finds himself landing on the head of a 6th-century black knight. Upon hearing of his miraculous appearance, the elderly King Arthur, seeing him as the savior Merlin predicted would appear, dubs the boy Calvin of Reseda and invites him to dine with the court. Calvin then begins his knightly training. When the earthquake hit, lucky Calvin managed to grab his knapsack and is therefore able to wow the Arthurians with his futuristic magic that includes an introduction to rock & roll via CD-player, and a wonderful Swiss Army knife. The young wizard also shows them how to make rollerblades. His work wins him adulation and renown, but it also rouses the jealousy of the wicked Lord Belasco who will use any means to take over the throne. Meanwhile, Calvin finds himself falling for young-princess Katey.
