The Oak Island Mystery, a 220-year-old search that has driven many to madness. Since the early 19th century, hundreds of wondrous souls armed with spades and diggers have headed to the island in the search for fortune, but none have prevailed.

It’s been four exciting years since the dig begun, and as Rick and Marty’s quest moves ever closer we are putting five of the most likely theories up for vote.
