In 1795, three teenage boys discovered a strange, man-made hole on Oak Island, a small, wooded island just off the coast of Nova Scotia, Canada. It is believed that the island is hiding one of the greatest treasures of all time, but no one to date has been able to find it. Rick and Marty Lagina, two brothers from Michigan with a life-long interest in the mystery of Oak Island, renew efforts to discover the legendary treasure with sophisticated machinery.
