Darrell and Cream make the first big discovery of the expedition as they follow new clues and Gordon Cooper's Treasure Map From Space to an area known as the "holy grail" of colonial era shipwrecks in the Bahamas.
Darrell discovers a 1700s-era cannon which sends him on a mission to make the debris path & determine the ship's origin. He reveals a letter Gordon's files detailing the find of a 16th century English wreck with a connection to Sir Francis Drake.
