Hoping to get answers about who carved the runestone, Peter Stormare and Elroy Balgaard meet with Scott Wolter, a forensic geologist who has studied the runestone for over 20 years.
Peter and Elroy take a closer look at the stone's history and how the Vikings traveled across the North Atlantic. They also meet the grandson of the man who found the stone and hear about the tragedies that have followed the family.
The boys meet Bob Voyles, a mysterious man who takes them to a hidden place where he says there are medieval artifacts buried, and learn more about how the Vikings traveled the world.
Scott Wolter calls the guys and tells them about a new scientific test that could prove Olof's innocence, but he needs their help to test the stone. They also receive the results of the DNA test.
Just as they are about to start digging at a promising archeological site, Peter and Elroy receive bad news and have to reconsider. They catch Darwin and learn a secret that gives them new hope.
The guys have finally gathered materials to carry out Scott's test. Darwin's tip leads them to find artifacts at the site where the stone was found. This could be the discovery that changes history.
Peter and Elroy start their archeological dig at Runestone Hill. They also meet Darwin who takes them to the cemetery where his grandfather is buried.
As the excavation continues, Peter and Elroy return to their investigation to clear Olof's name. They meet a professor who gives them new knowledge of the area and his tribe.
With many new clues to follow, they head to the East Coast to take a closer look at engravings that may provide more answers. They also meet the historian Sturla Ellingvåg, who takes them on a boat trip.
Finally they get to see the famous Maine Penny and the visit to the Maine State Museum opens their eyes to new possibilities. Afterwards they meet the anthropologist Harald Prins.
After an intense search for more hard evidence, Peter and Elroy choose to go in a different direction with the investigation. Each object leads them deeper into a web of mysterious symbols and conspiracies.
The East Coast adventure is coming to an end. Peter and Elroy reflect on what they have found and learned along the way, while a new plan begins to take shape.
