The team is looking for the Sacred Chalice and the treasure of Cavaliere Piamonte on behalf of tbhe Vatican when Brother John (from "The Angel of St. Edmunds") shows up being chased by bad guys. 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 get the treasure and attack the house. The team find a vault with the treasure and Judson gets the drop on the attackers after everyone else gets captured and a bomb planted on them – it turns into a Mexican standoff until the others drop the police chief and Mackenzie manages to toss the bomb in a fish tank. John takes off and the chalice goes back to the Vatican.
