Sister Therese is faced with a problem. The castle she is caring for has been taken over by the Imperial Army, and Captain Prince Mefist is turning her world upside down. He is going to billet soldiers in her domain, and that is not the worst of it. He will have officers staying in the family apartments, and he wants to set up a bordello in the attic.
Therese is left alone to keep the soldiers away from her nuns, and protect the village people from the Army's depredations...
