Are you ready to face your fears? That is the question being posed to all who respond to a newspaper ad requesting participants who think themselves brave enough to spend one night in a reputedly haunted castle in Scotland.

As their night of terror progresses and the participants begin to disappear one by one, it becomes painfully obvious that the resident spirits within are willing to go to any lengths to assure that few, if any, will be walking out alive the following morning.
