Ivo the orphan, together with the Hag of Dribble, Ulf the Troll, and Brian the Wizard, sets out to save Princess Mirella from the dreaded Ogre of Oglefort. But when the rescuers arrive at the castle, they are shocked to find that the princess doesn't want to be saved; she wants the ogre to turn her into a bird so she can escape an arranged marriage. And the Ogre isn't nearly the fearsome creature he once was—in fact, he's rather depressed. Now the rescuers have a new goal: save Princess Mirella from her tyrannical royal family and help restore the Ogre and his castle to the fearsome (but fun) paradise it used to be.
