Matty Blake treks to Oak Island to take a look at the team’s latest and most epic operation yet, as well as get new insight from brothers Rick and Marty Lagina on the many highlights from the first five years of their quest.

The lead cross and the red gemstones are only the latest artifacts discovered in the 223-year-old treasure hunt. This special takes viewers back to the very beginning of the hunt, chronicling the discoveries of generations of searchers.

Ever since the discovery of the Money Pit, Oak Island has been closely linked to colorful tales of pirates. Did they land on Oak Island more than 200 years ago and bury an incredible treasure? This one-hour special episode drills down on the myths, legends and compelling evidence that pirates were behind the world’s longest treasure hunt.

In the past 10 years, Rick and Marty Lagina–along with their partners, Craig Tester and Dan Blankenship, have made some incredible discoveries. But they would be the first to tell you they didn’t make all these discoveries on their own. In this special, we focus on a group of guys who have become Oak Island’s “secret weapons.” Gary Drayton, Charles Barkhouse, Doug Crowell, Paul Troutman, Dan Henskee and Tony Sampson.

Matty Blake joins the Laginas and members of the Oak Island team in Michigan to hear the shocking results of the seismic testing done in the swamp. And in a moving tribute, the brotherhood of the dig remembers Dan Blankenship.
