The story of Lancelot and Guinevere's adulerous affair and its catalyst in the collapse of Camelot and the Knights of the Round Table. Loosely adapted from the Lancelot-Grail cycle and the works of Chrétien de Troyes, the film portrays Arthurian legend stripped bare, unglamourous and bloody, the characters cruel and proud. It's beautiful, mesmerising, haunting, uplifting, amazing, stylish - all the things you would expect from a masterpiece.
