Drama-documentary telling the story of one of the last trials by battle to be fought in Europe, a tale of sex, brutality and political machination set in 14th century medieval France. A knight, Sir Jean de Carrouges, accuses his former best friend, Jacques Le Gris, of raping his wife Marguerite. Unable to obtain justice from his feudal overlord, Carrouges appeals to the king for the ancient right to fight a duel to the death to find out God's truth. There is much at stake. If Carrouges dies in the battle, Marguerite will also be burned to death as a liar. This tense story, told from records of the day, is set against the backdrop of the 100 years war between England and France, 14th century attitudes towards women, crime and punishment and the political intrigues of the feudal system.
