In the wake of King Uther’s sudden death, chaos threatens to engulf Britain. When the sorcerer Merlin (Joseph Fiennes of Shakespeare In Love) has visions of a dark future, he installs the young and impetuous Arthur (Jamie Campbell Bower of the Twilight series), Uther’s unknown son and heir, who has been raised from birth as a commoner. But Arthur’s cold and ambitious half-sister Morgan (Eva Green of Casino Royale) will fight him to the bitter end, summoning unnatural forces to claim the crown in this epic battle for control. These are dark times indeed for the new king, with Guinevere (Tamsin Egerton of The Mists of Avalon) being the only shining light in his harsh world. Faced with profound moral decisions, and the challenge of uniting a kingdom broken by war and steeped in deception, Arthur will be tested beyond imagination. Forget everything you think you know…this is the story of Camelot that has never been told before.
