An ancient prophecy says that King Fudd the Bewildered will die peacefully, with his daughter at his side during his last hour.

Princess Lorealle the Worthy then mysteriously disappears after being abducted by her stepmother, Morgana, who wants her own daughter on the throne.

To keep the princess from being rescued by a valiant knight, Morgana ensures that the Union Hall chooses the most unworthy one for the task: Eric the Unready, who is known for bringing the book How to Joust to his duels.
