This documentary travels across the world, from Rome to India, Portugal to Egypt, uncovers the trail of the Ark of the covenant and finds that it does not lead to Ethiopia, as many believe, but instead in a direction that nobody could have imagined. The trail of the Ark takes Gardiner on a hunt into the very heart of an ancient secret society with clandestine meetings in far off lands. Uniting the myth, tradition, and language of the Ark with the Shroud of Turin, Gardiner then goes on to re-date it, reveal how it was made, and identify whose image it actually recreates.
Through his new-found contacts in the world of secret societies, Gardiner then shows how this incredible secret was protected by a dual brotherhood throughout time and was the secret source of the enlightenment spoken of by numerous orders from the Sufis to the Knights Templar.
