In a medieval, but futuristic, world, young knights Clay, Aaron, Lance, Princess Macy and Axl are tasked with protecting the kingdom of Knighton from Jesto and the army of Lava Monsters. The evildoers are searching for magic books; with each one they acquire, they become more powerful. Jestro uses the strength he gains from the books and his minions to capture knights to make it easier for him to attack the king's castle. It's all part of Jestro's ultimate plan of defeating the king and taking over Knighton as the land's new ruler.
