The Carpathian Mountains, 1897. An impassable storm forces a group of travellers to disembark from their steam train and take shelter in a remote castle for the night. Their enigmatic host invites them to take part in some after-dinner entertainment. But as they each explore the castle's rooms and passageways, they discover they have become part of a deadly game. Only one guest may leave in the morning and it is up to each of them to use their wits, and weapons, to survive the night. For the others, Damnation awaits.
