The White Castle: The Fantastic Voyages of Jack Flanders

Jack and his crew accept an invitation from an eccentric billionaire who has built a castle on a Carribbean island. What first appears to be a replica of a medieval fortress turns out to be a very high tech castle, with robot valets, and rooms with floor-to-ceiling plasma screens. In the middle of the night, Jack's crew begins to encounter their own "personal demons", first in their dreams and then right before their eyes.
