Host Brad Meltzer and viewers are on the hunt for lost and stolen history. Among the missing: an historic plaque commemorating Alex Haley’s epic slave history Roots, stolen from a port in Annapolis–possibly by the Ku Klux Klan. Then, FBI agents search for criminals trying to sell North Carolina’s original copy of the Bill of Rights; plus: a mysterious ring worn by Lee Harvey Oswald the morning that John F. Kennedy was assassinated.
