Bletchley Park was once one of Britain's best-kept secrets. During WWII, the mansion was Churchill's intelligence and computer headquarters, a place where enemy communications were decrypted, shaving years off the war. Today it's a heritage site, recently restored for the 70th anniversary of D-Day. A behindthe-scenes tour led by a team of experts with complete access to the building and its history, this documentary includes interviews with veterans who were there and helped to break the Enigma code. 80 min, 1 DVD
