Dr. Magnus, Will and Ashley rescue three attractive young women from a tomb that is well guarded by violent creatures. The three women - Danu, Tatha and Caird - all claim to be from the Middle Ages but Will is having none of that and is convinced that they are suffering from the same delusion. Dr. Magnus thinks otherwise if for no other reason that the women were kept under a heavily armed guard. The women all wear the same ring and the symbols point to their enemy who want the women back - and who are prepared to destroy the sanctuary to get them.
