Aired: April 05, 2009

The naval base at Guantanamo Bay secured a place in the annals of history when the first wave of detainees from America's War on Terror – men dubbed "the worst of the worst" – arrived in 2002. The goings-on inside the wire encircling this highly classified camp have been a closely held government secret — until now. National Geographic exclusively captures day-to-day life in the most famous prison in the world.
