Lord Belasco is a pompous arrogant traitor to Camelot who wants Princess Sarah and he plans to abduct her and threaten to kill her sister if she refuses.
Lord Belasco is also very conceited, he challenges Calvin to combat no matter what the situation is and he has a score of loyal knights who will stop at nothing to ensure his success.
Belasco kidnaps Princess Katie, sister of Sarah and takes her to his castle wherein Calvin realizes that King Arthur had been duped and Belasco was a traitor. He and Arthur go to get his daughters back and fight Belasco's men.
Lord Belasco is surprised his plan was thwarted but engages in a tournament to legally wed Sarah and take over the kingdom. Lord Belasco wins against each champion but is defeated eventually by Calvin in the tournament and Princess Sarah, who pins his cloak to the ground with an arrow, just when he is about to kill Calvin. King Arthur banished Belasco from Arthur's kingdom and Camelot for good.
