Nazi Spies in America (History Channel)

The attacks on September 11, 2001 did not mark the first time foreign nationals were secreted onto American soil. At the height of WWII, 8 German saboteurs crossed the Atlantic in a pair of U-boats, surfacing on the eastern shore with plans to attack, destroy, and terrorize. When captured, 6 of the 8 were executed, while the ringleader languished in prison. Recently declassified FBI documents paint a new portrait of the doomed mission and offer a surprising account from the spies' point of view.
