For nearly two centuries, the Knights Templar were the most powerful order in the Medieval world, a fearsome and unstoppable Crusader militia. Then came accusations of unspeakable crimes. Who were the Templars, really?

How did they become so powerful, so fast, and why did they fall just as quickly? Evidence hints that the Templars excavated under Jerusalem’s Temple of Solomon. What did they find there? Was it, as The Da Vinci Code suggests, the true identity of the holy grail, the bloodline of Christ? Or an unimaginable treasure, documented in the Dead Sea Scrolls, buried a thousand years before the birth of Christ?

This documentary explores where the Templars came from, how they lived, trained, fought and became a Medieval world power, and the suspicious circumstances behind their sudden downfall. Find out why the Templars are tied to the story of the Holy Grail and what treasures may still be buried in secrecy. Biblical scholars examine the link between this order and Jesus Christ. Ed Herrmann hosts this investigation into one of the most unique orders the world has ever seen.
