As he chases Sammy through the trees, he enters an amazing place - the kingdom of Terra Libre. Sir William, a Master Knight, offers to train Max in the art of knighthood and Max wants nothing more than to learn to sword fight, but the path to knighthood is more difficult than he could have imagined. When danger strikes, Max has a choice to make. Will he stay in Terra Libre and become a knight? Or will he be able to find Sammy and return home in safety? One thing is for certain, Max will never be the same again!
