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.

Forgotten clues produce new leads as the fellowship of the dig zeroes in on the Money Pit.

After 152 years, the Money Pit may no longer be lost.

New evidence suggests the swamp may be man-made on a scale the team never could have anticipated.

Excitement abounds when Gary uncovers what could be a "friend of the cross."

With a dangerous hurricane approaching, the team scrambles to find evidence of what might be buried beneath the swamp before the storm can wipe out their efforts.

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 manmade 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, hard evidence suggests that Fred Nolan's theory that a ship was buried in the swamp centuries ago, may 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.

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

New analysis connects man-made activity in the swamp to the construction of the Money Pit just as the team begins their most ambitious and expensive operation yet to locate the elusive treasure shaft.

Exciting finds bring new excitement, but the team must move quickly since time is running out before they must suspend operations for the harsh winter ahead.

While the brotherhood gets closer than ever to the original Money Pit, new discoveries suggest the flood tunnels were not the only traps set to thwart searchers.

The Restalls return to Oak Island with exciting new artifacts while Rick, Marty and the team reach new depths in the Money Pit in their final push before winter.

With time running out, the ultimate breakthrough may be within the fellowship's grasp, and new evidence suggests Samuel Ball was guarding something of great value.

It's the end of drilling season on Oak Island and after a year that saw the fellowship make a number of groundbreaking discoveries in their quest to solve a 225-year-old treasure mystery, the team is determined not to leave the island without making at least one more historic breakthrough.
