For hundreds of years, Oak Island, on the North Atlantic coastline, has fascinated historians and treasure hunters alike. Over the years, evidence pointing to a mysterious long-buried treasure has brought hundreds to the small island to seek out its fabled riches sometimes, with deadly results. Now, brothers Rick and Marty Lagina's lifelong fascination with Oak Island has culminated in the most extensive research project in the islands history. Over six seasons, the brothers and their dedicated team have harnessed cutting edge technology, a tireless work ethic and good old-fashioned grit in an attempt to reveal the islands long-held secrets. But always in their mind is the infamous curse that surrounds Oak Island: that seven men must die before the legendary treasure is found. Last time the brothers counted, that number stood at six.
