An attorney arrives at a castle to settle the estate of its recently deceased owner. The owner's wife and daughter reveal that he was someone who was able to summon the souls of ancient plague victims and, in fact, his spirit was roaming the castle at that very moment. Soon occupants of the castle begin to die off in gruesome, violent ways.
