Loading where to watch…

In 1795, three teenage boys discovered a strange, man-made depression in the ground on Oak Island–a small, wooded island just off the coast of Nova Scotia, Canada. As the boys began to dig, they found a number of intriguing artifacts. It was the end of the piracy era and rumors of buried treasure were rampant. The boys’ discovery launched a treasure hunt that has spanned more than 200 years.The search had gone dormant, but last year, Rick and Marty Lagina, two brothers from Michigan with a life-long interest in the mystery, renewed the efforts to discover the legendary treasure.

After dating the Spanish coin they found last summer to 1652, brothers Rick and Marty Lagina return to Oak Island and the strange triangle-shaped swamp to look for more clues to this 200-year-old mystery.
