Explorer and history buff, Don Wildman, is on a quest to find the forbidden, hidden and unseen spaces across America. With a take-no-prisoners approach, he'll unearth the truths of our past and find their secret connections to our future. Don will get insider access to off-limits mega structures, crumbling mines and abandoned factories in pursuit of mystery and revelation. He will drop down factory smokestacks, scale fortress walls, climb ropes to survey meeting grounds, and venture into Al Capone's underground speakeasy in Chicago and the Ordinance Works bunkers used to build bombs in WWII outside St. Louis.
