Sailing, scuba diving and beautiful weather. It seems like a great impromptu vacation for Will and his cousin Harley. But the vacation turns into a battle with crooks who are searching for a centuries-old treasure. When Will and Harley arrive by yacht in Bermuda, they find themselves forced at gunpoint to dive for a Civil War blockade runner that is said to have sunk laden with gold. As they try to foil the plans of the treasure seekers, the cousins learn about the shipwreck, the Civil War blockades and family history.
