The Holy Grail is one of the most sought after treasures of all time, and one treasure hunter thinks he knows exactly where it is. He invites Scott Wolter along on his quest to find it, and the result is a North American treasure hunt of epic proportions. Legends, a treasure map and the results of ground penetrating technology all point to the Grail being in a single location--a holy well on the property of a rumored Templar Prince. What Scott finds in and around the well will shock even the skeptics in this edge-of-your-seat season finale.
