Chalus Chabrol, 1199. The Occitanian knights battle for their lives against Richard the Lionheart. They are guarding the Blue Flame under which all Occitans must unite to resist invasion. But the knights cannot survive and so it falls to Parsifal, young son of the knight Bernard, to travel on alone and find the true keeper of the Flame. Yet when Parisfal returns home, the Occitain is ablaze, Catholic inquisitors and Cathar heretics, far from uniting, are fighting each other for the soul of the land. Parisfal's path intertwines with Raimon, son of Cathar weaver, and Yolanda daughter of Catholic count. They are falling love, but in a time of hate, love is never left in peace.
