Three children, forced to remain at school during the holidays, go in search of adventure. What they find is a magic castle straight out of a fairy tale, complete with an enchanted princess at the center of a maze. Or is it? The castle turns out to be just a country estate, and the princess is only the housekeeper's niece, playing at dressing up. But the magic ring she shows them proves—to her surprise and horror—to really be magic. Soon they are caught in an adventure where statues come alive, lost lovers are reunited, and wishes can be granted—but always for a price.
