The Curse of Oak Island Season 4

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, cost millions of dollars and involved dozens of speculators, engineers and even famous personalities such as John Wayne, Errol Flynn and Franklin D. Roosevelt. It has also cost six men their lives. According to legend, a seventh must die before the mystery will be solved. The search had gone dormant, but Rick and Marty Lagina, two brothers from Michigan with a life-long interest in the mystery, renewed the efforts to discover the legendary treasure.
