Le mystère d'Oak Island

After a decade of searching, Rick, Marty and the team return to Oak Island and immediately uncover evidence of a mysterious tunnel in the Money Pit.

While on a research mission in England, Marty, Alex and Charles are thrilled to uncover more evidence connecting the Knights Templar to the Oak Island mystery.

Armed with more evidence that the garden shaft is connected to a possible series of tunnels in the Money Pit, the team begins the arduous work necessary to get a team member underground.

The team is astonished when Gary unearths multiple artifacts in close proximity to the old ship's wharf. And Marty's theory of an off-set chamber may finally be proven.

The discovery of mysterious ship logs provides more evidence suggesting a 1746 French armada led by the Duc D'Anville landed on Oak Island.

Gary unearths a curious artifact on Lot 8 and in the Money Pit, the team is astonished to discover that they may be chasing multiple tunnels towards the gold in the garden shaft.

The team returns to the swamp and uncovers more evidence of a sunken ship. And in the Money Pit, the discovery of a collapsed structure could mean they have finally located the off-set chamber.

The team's high hopes of finding the fabled treasure are intensified when they procure what could be the final piece of the puzzle.

The fellowship is stunned when evidence suggests that a dam lies buried at the end of the swamp, corroborating both Fred Nolan's theory and Zena Halpern's Templar map.

While the archaeologists work hard to uncover a new feature discovered on Lot 5, the scientists have finally identified the area where the gold is.

While the team uncovers more evidence suggesting the mysterious man-made stone foundation on Lot 5 was purposefully hidden, the Fellowship is zeroing in on the gold in the Money Pit.

While the team searches for clues to understand why an ancient well was constructed on Lot 26, excitement abounds when more evidence of a tunnel is discovered.

As the Fellowship prepares to get a team member underground in the Money Pit for the first time, a new theory emerges suggesting that Nolan's Cross holds the secret to its exact location.

The team is ecstatic when new scientific evidence narrows down the location of the gold signature in the Money Pit. And Rick realizes a lifelong dream when he finally gets underground on Oak Island.

As the garden shaft operation gets deeper, the evidence of gold gets stronger.

While the drilling operation gets closer and closer to its destination, the team is shocked when they discover evidence of an ancient safe.

After a long wait, the Fellowship finally gets permission to return to their excavation in the swamp. They make a discovery that could connect all the cobblestone dots in the mysterious bog.

As time is running out, an exciting find in the swamp may have the fellowship rewriting the history of North America.

After a new find suggests that the Oak Island mystery could have ties to Italy, the team investigates a stone structure that has a design that matches the original Money Pit treasure shaft.

Winter is quickly approaching but the swamp reveals more of its secrets, and a trip to Italy provides a shocking new insight into Nolan's Cross.

While an incredible new discovery is made in the triangle-shaped swamp, Rick and members of the team make shocking connections in Italy between the Knights Templar and the Oak Island mystery.

Rick, Marty and the team make a discovery below the Garden Shaft that could be the key to solving the Oak Island mystery.
