From centuries-old subcultures with secret chapters across the country to modern members-only clubs that exist only through word of mouth, each episode of Destination America's new anthology series HIDDEN IN AMERICA travels behind the veil of secrecy to explore a corner of society with a name viewers might recognize but an M.O. that's a huge unknown. Featuring interviews with individuals directly affected by the groups, either through their own belonging or that of a loved one, these first-hand insights breathe a gripping reality into communities largely shrouded in mystery and legend. HIDDEN IN AMERICA kicks off on February 17 at 10 PM E/P with "Mongols Motorcycle Club," followed by "Underground Fight Clubs" on Saturday, March 9 at 10 PM E/P and "Mormons" on Sunday, March 10 at 10 PM E/P.
