Mysterious Castle of Dr. X

Circa the late eighteenth century, six tourists from Vienna, 'the big city,' arrive in the backwoods of Transylvania by horse and carriage on holiday and in search of a quaint rural adventure among the common folks. A detour leaves them stranded atop a mysterious decrepit, old castle populated by odd noises and an eerily suspicious servant. Along the way, they encounter a colorful thief, strange mutant-like beings, and a beautiful young lab assistant who may not be as she appears. Amid their own bickering, the tourists are led about the castle by the doctor himself, one step behind him and his diabolical plans. Now they must try to survive a stormy night within the mysterious castle of Dr. X.
