In Albuquerque's National Museum of Nuclear Science and History, there's a small antique vial that once contained a wildly popular drug called Radithor. How did this doctor-approved "cure-all" end up destroying countless lives?

Inside Chicago's Museum of Science and Industry there's a giant World War Two Submarine. It's a German "U-Boat", known by its infamous number, 5-0-5. But during the war U-505 mysteriously vanished. How did U-505 end up in Chicago, and how did its sudden disappearance from battle nearly 70 years ago help bring Germany's invincible U-Boat fleet to its knees?

Secured in the archives of the New Jersey State Police Museum is a faded piece of paper inscribed with sloppy handwriting and a curious insignia. It's a ransom note from what's been called "The Crime of the Century."
