Buried: Knights Templar and the Holy Grail S01 E03 Surviving the End

Armed with insight into two centuries of Templar survival strategies and battle tactics, the team turns their attention to the Templars moment of reckoning: the fall of the order in 1307. They find evidence of a Templar smuggling operation to save their treasure and relics before the fateful day of Friday the 13th, when knights all over France were arrested. Coded Templar symbols lead the team to a mysterious monastery in Spain that may hold clues to the knights’ ultimate survival as a secret organization.
