Prison Ploy, Enigma Machine, Mona Lisa

This episode was narrated by Jay Thomas.

Alcatraz. Once America's most notorious prison now houses four makeshift, dummy heads. Painstakingly crafted and topped with real human hair; how did these masks help destroy the reputation of America's most formidable prison? The Enigma Machine is among the many guns, planes and chilling machines of war at the National Museum of the Navy. How did this machine help to win World War Two? And is Walter's Museum of Art in Baltimore, Maryland the actual home of the Mona Lisa?
