Plot synopsis: Twenty years ago, the Count of Groningen left his ancestral castle. Since then, it is said to be haunted. Shortly before his escape from the dark walls, the Count had left his newborn child to the care of the administrator and farmer Grödner. The nasty Grödner had already swapped his own child Veronika with the Count's in the cradle, probably because he hoped to one day gain possession of the castle.
