Armed with new evidence suggesting a ship is buried in the swamp, Rick, Marty and the team return to Oak Island determined to honor Dan's legacy by solving the centuries old mystery once and for all.

After years of speculation, new scientific evidence suggests the swamp is manmade.

Gary detects a strange, stone structure embedded in the swamp and after years of searching and speculation, the Laginas get scientific proof that the swamp is young and likely manmade.

After years of searching, the team believes they have found the elusive flood tunnel that will lead them to the Money Pit and Gary discovers a mysterious artifact that may have a connection to the Founding Fathers.

New evidence suggests there was French activity on Oak Island decades before the discovery of the Money Pit and the team may have finally uncovered definitive proof the swamp was man-made centuries ago.

Excitement abounds when Gary uncovers an ancient tunneling tool in the swamp, and the team obtains hard, scientific evidence suggesting they may have finally located the original Money Pit.

New evidence suggests that Fred Nolan's theory that a ship was buried in the swamp long ago might be true.

The team may be closer than ever to shutting down the flood tunnels when they discover large amounts of coconut fiber in the uplands. And a compelling new theory suggests the original trio that discovered the Money Pit in 1795 did not come upon it accidentally.

The fellowship of the dig doubles down on their efforts in the swamp and discover that it might hold the key to solving the entire Oak Island mystery as Fred Nolan predicted.

The time to investigate the uplands of Smith's Cove is quickly running out, so Rick goes to extreme and dangerous measures to get answers.
