"In Germany - beyond the sea - stands a castle high on a mountain. You can look down into a lovely valley from its walls. It is crossed by the river Unstrut. During the day, the castle is alive and filled with the sounds of the many visitors greeting their friends, children playing and laughing and the workers going about their daily business. But as soon as dusk falls, everyone flees the old walls. The cheerful sounds of daytime vanish and all that is left is an eerie, deafening silence." Scotland is the land of castles and great knights. They neither fear battle nor monster.

This is the story of a young brave Scotsman who freed the German valley of the river Unstrut from a terrible plague.
