After last year's devastating flood in the garden shaft, Rick, Marty and the fellowship return to Oak Island with renewed confidence and immediately discover a never before known shaft.

In the swamp, the team uncovers a previously unknown structure remarkably resembling a container. And after weeks of chasing the elusive Chappell Vault, the Fellowship hits a void deep in the Money Pit.

As the Fellowship uncovers more of the mysterious structure in the swamp, artifacts within it suggest it could be a vault with a compelling history.

The team is ecstatic when a newly discovered treasure map turns out to be more accurate than they could ever have imagined.

After months of tireless work and focused research, the massive excavation to recover the fabled Chappell Vault begins.

As new research identifies who may have been behind the Oak Island mystery, the Laginas and their team are stunned by what they find in the Money Pit area.

New ground penetrating radar uncovers evidence of more structures in the swamp and as winter approaches, the team puts a daring plan together to get into the Solution Channel for the first time.

While the team races against the impending winter to get into the Solution Channel and finally retrieve the treasure on Oak Island, Rick and members of the fellowship make new connections 4,000 miles away in Malta.
