The Last Crusader of San Giovanni - S1.E19

The team is looking for the Sacred Chalice and the treasure of Cavaliere Piamonte on behalf of the Vatican when Brother John (from "The Angel of St. Edmunds") shows up. They also run into Don Nicosia who warns them off and whose daughter is attracted to John. The team track the treasure to a tombstone and are attacked and the tombstone stolen. They manage to track it from a fragment to the Don's land but John gets captured by the Don's men – when they meet with him, the Don is amenable to turning over the treasure in return for his name on the donation, but the local police chief and his men, descendents of the templars, intend that no one gets the treasure.
