A powerful hurricane forces Jeff's team into a secluded cove, where they investigate The Lombrac, a legendary 18th-century ghost ship. As the divers recover intriguing clues from the murky depths, Jeff zeroes in on the site of a 300-year-old mystery that may finally be solved.

Third-generation shipwreck hunter Jeff MacKinnon embarks on a daring quest along the infamous Death Coast—a merciless stretch of the North Atlantic that has swallowed thousands of ships for centuries. Among them: Le Chameau, an 18th-century French cargo and passenger ship that sank with a fortune in rare coins. Armed with a 300-year-old map and backed by a world-class team of divers, Jeff races against time—and the unforgiving ocean—to recover the Chameau's lost treasure before the relentless storms of the Death Coast shut him down.
