Fresh off their recent success in the West Indies. The Concord crew and the Philadelphia embark on a routine mission escorting a convoy carrying their family to Malta and Trieste. A special American envoy in the Concord is to meet with the Knights of Malta. At the fruitful conclusion of the meeting with the Knight's Grand Master, they will continue to Trieste, with plenty of time to spare before the upcoming wedding. But the French have other plans which will bring the captain and his officers to their very limits to ensure success and avoid capture.
