The Keep is a story about two cousins involved in a haunting business venture that evokes a horrifying tale from their past.

His cousin Howard presents him with an opportunity to come to Eastern Europe and help convert an old castle into an alternative resort.

Many years before, when they were children, he cruelly left Howard stranded deep in a cave for days, traumatizing him badly, and ruining much of his childhood.

But Danny is desperate for money, so he decides to work for Howard and travels to the castle, severing his relationships with his New York world.

Danny, cut off from his familiar New York world, is unsure whether the castle is haunted or his own perceptions are becoming increasingly distorted.
