The miniseries deals with two women , modern-day Alice Tanner (Vanessa Kirby) , a volunteer at a French archaeological excavation who finds the skeletal remains of two people in a cave , and medieval Alaïs Pelletier Du Mas (Jessica Findlay) , who lives through the Crusades and Cathar slaughters in medieval France , both of them are seeking the Holy Grail . As there are three sacred books that reveal the secret of the Holy Grail from the Crusaders and various tracks as a labyrinth-engraved ring that lead to resolve the enigmas . In 1209, newly married Alaïs to Guilhem Du Mas is living in Carcassonne , a stronghold of Cathars defended by Viscount Trencavel (Tom Felton). Meanwhile , it is besieged by Simon Monfort (John Lynch) and Guy D'Evreux (Tony Curran) leaders of the Crusaders . Hunted by the Inquisition and deserted by the nobles of their districts, the Cathars became more and more scattered fugitives : meeting surreptitiously in woods and mountain wilds .
This is an epic film mingling actual events along with past happenings by means of a lot of flashbacks ; as while in contemporary time occurs an intrigue starred by Vanessa Kirby , in Middle Age when the city of Carcassona has been declared heretical by the Church being starred by Jessica Findlay , and his nasty sister Katie McGrath . The most interesting moments concern about the historic events dealing with Catharism , a movement that thrived in some areas of Europe , particularly southern France, between the 12th and 14th centuries , the followers were known as Cathars and are now mainly remembered for a prolonged period of persecution , it appeared in Europe in the Languedoc region of France , as here are shown impressive battles and strong massacres , they are the highlights of the movie . Acceptable mini-series , though sometimes result to be pointless , non-sense , and confuse . Based on the bestseller by Kate Mosse who plays a small role as Montsegur Guide . The picture was professionally directed by Christopher Smith , though it has some flaws and gaps .
This one being based on historic facts as : Pope Innocent III attempted to end Catharism by sending missionaries and by persuading the local authorities to act against them . In 1208 Innocent's papal legate Pierre Castelnau was murdered while returning to Rome after excommunicating Count Raymond VI of Toulouse . Pope Innocent III then abandoned the option of sending Catholic missionaries , launched the Albigensian Crusade which all but ended Catharism . The crusader army came under the command, both spiritually and militarily, of the papal legate Arnaud-Amaury. In the first significant engagement of the war, the town of Béziers was besieged . The Catholic inhabitants of the city were granted the freedom to leave unharmed, but many refused and opted to stay alongside the Cathars. Their first target was the lands of the Trencavel, powerful lords of Albi, Carcassonne and the Razes—but a family with few allies in the Midi. Little was thus done to form a regional coalition and the crusading army was able to take Carcassonne, the Trencavel capital, incarcerating Raymond Roger Trencavel in his own citadel where he died , allegedly of natural causes; champions of the Occitan cause from that day to this believe he was murdered . Simon de Montfort was granted the Trencavel lands by the Pope and did homage for them to the King of France, thus incurring the enmity of Peter II of Aragon who had held aloof from the conflict, even acting as a mediator at the time of the siege of Carcassonne. The remainder of the first of the two Cathar wars now essentially focused on Simon's attempt to hold on to his fabulous gains through winters where he was faced, with only a small force of confederates operating from the main winter camp at Fanjeaux, with the desertion of local lords who had sworn fealty to him out of necessity—and attempts to enlarge his newfound domains in the summer when his forces were greatly augmented by reinforcements from northern France, Germany and elsewhere. Summer campaigns saw him not only retake, sometimes with brutal reprisals, what he had lost in the 'close' season, but also seek to widen his sphere of operation—and we see him in action in the Aveyron at St. Antonin and on the banks of the Rhone at Beaucaire. Simon's greatest triumph was the victory against superior numbers at the Battle of Muret—a battle which saw not only the defeat of Raymond of Toulouse and his Occitan allies—but also the death of Peter of Aragon—and the effective end of the ambitions of the house of Aragon/Barcelona in the Languedoc . The Battle of Muret was a massive step in the creation of the unified French kingdom and the country we know today—although Edward III, the Black Prince and Henry V would threaten later to shake these foundations. The Cathars spent much of 1209 fending off the crusaders. The Béziers army attempted a sortie but was quickly defeated, then pursued by the crusaders back through the gates and into the city. The doors of the church of St Mary Magdalene were broken down and the refugees dragged out and slaughtered. Prisoners were blinded, dragged behind horses, and used for target practice. What remained of the city was razed by fire. After the success of his siege of Carcassonne, which followed the Massacre at Béziers in 1209, Simon de Montfort was designated as leader of the Crusader army. Prominent opponents of the Crusaders were Raymond Roger Trencavel, viscount of Carcassonne, and his feudal overlord Peter II, the king of Aragon, who held fiefdoms and had a number of vassals in the region. Peter died fighting against the crusade on 12 September 1213 at the Battle of Muret. Simon Montfort was killed on 25 June 1218 after maintaining a siege of Toulouse for nine months .
