A party at the home of a respectable socialite sets in motion a sequence of events which lead a group of reluctant companions on a quest for King Arthur's tomb.
Martin Owen is a mild mannered accountant, ignored and disrespected, even by his own family. But an experiment in hypnotic regression wakens a mysterious long dormant spirit from the time of Arthur. Intrigued, the party's guests are drawn in further slowly forming an impromptu team on the trail of buried Roman treasure and the forbidden secrets of Camelot. Each interrogation of the sleeping spirit, leaves it encroaching further and further upon Martin's life, until we are unsure who is controlling who. Meanwhile, the romances, ambitions, illicit affairs and secrets of each of the party members are exposed as the shadow from the past inexorably leads them to glory or doom.
