Two mighty kingdoms are engaged in endless, merciless war, but change appears imminent. King Philip is meeting his archenemy, King Theodo, to sign a peace treaty. But King Philip and his men are tricked and consigned to the squalid dungeons of King Theodo's castle. Soon, his son, 12-year-old Prince Florin, is lured to the castle, where the same horror awaits him. On a whim, King Theodo decides to make the captive crown prince his second Fool, trained by Mimus, an enigmatic, occasionally spiteful, and unpredictable court jester. To add to Florin's misery, he and Mimus are fed a daily portion of gruel, forced to live in a dark, damp tower, and required to entertain the court on demand. But events ultimately turn for Florin and the other captives. They escape and it is Mimus's intervention that helps make it possible.
