December 1939. A train winds its way through Italy towards the
Alps with a cargo too precious to destroy, too awful to reveal. On

Its sinister contents, documents concealed for centuries, could rip

people against another. Now, as the Nazi threat marches closer, good
men and evil are drawn into a violent and deadly hunt. The richest
aristocrat in Italy is responsible for the documents' safety, but he's
marked for death by the Nazis.
Some people want the secrets told. Some people want to plunge the world
into a catastrophic holy war...
