Buried: Knights Templar and the Holy Grail

Seven years after the alleged end of the Templars, signs the knights were rising again appear in Portugal.

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.

An investigation into the true fate of the Knights Templar begins in Jerusalem, where tunnels and a safe house may have been used to move holy relics to safety during the fall of the city.

In Acre, Israel, the team goes underground to investigate the purpose of the Templars' tunnel system, theorizing they may have contemplated a covert landing in sea caves.
