Adventure Inc. is recruited by St. Edmunds Abbey to retrieve a stolen gold and jeweled Angel that is believed to carry protective powers. They are contacted by a monk, Brother John, who is sworn to silence and thinks he knows where the Angel is. The trail leads to London where mobsters try to take out Lucy Wyle, a bar and casino owner who has the Angel and refuses to sell it.
The team seeks the treasures of the Knight's Templar on behalf of the Vatican. Along the way, they meet an old friend. The officials want them to stop their search, and Adventure Inc starts to suspect the Knight's Templar is still alive and active.
