4x5 - The Curse of Oak Island: Drilling Down

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.
