Storyline

Mac sees a unique ring on Grandpa's finger which prompts the story about their ancestors who became knights after learning the values and battle techniques as squires. Squires receive this ring once they have proven their skills. However, Grandpa tells the story of one of the squires, Mackenzie, who saved the castle from a dragon with an innovative idea.

Mackenzie assists the knight, Sir Galahad, and two other knights who go into battle with the dragon. Unfortunately, the knights do not succeed. The villagers believe they are doomed. Though the squires have much to learn, they feel they know how to engage the dragon and protect the castle.
