Forensic geologist Scott Wolter investigates the mysterious history of the Knights Templar, a powerful medieval order that was brutally suppressed on Friday the 13th in 1307. Wolter travels across the globe to uncover hidden symbols and artifacts that suggest the Templars may have possessed a dangerous secret regarding the bloodline of Jesus and Mary Magdalene, and that they may have even brought this knowledge to America. Through his investigations, Wolter challenges the established historical narrative, seeking to reveal the truth behind the Templars' mission and their enduring legacy.
