A screenwriter in Austria doing research for a documentary on Hitler, makes startling discoveries about Hitler's birth and family. After leaving copies of his notes at St. Stephans Cathedral for safekeeping he heads for Argentina and disappears.
Thirty-five years later, a young American reporter sent to Vienna to gather information the global rise of Nazism also disappears. The paper's star reporter is sent to Vienna to investigate his disappearance and finds the screenwriter's notebooks in the catacombs beneath St. Stephans.
Clues in the notebooks send the reporter and his pretty photographer on a dangerous trail that leads them to Buenos Aires where attempts are made on their lives and a chance discovery provides more clues. Folklore and satellite photos provide them with the location Vida Largo, a legendary Shangri-La like village hidden high in the Andes mentioned in the screenwriter's notes.
They make the perilous climb to Vida Largo and learn that the answer to who is coordinating and financing the new Nazi order lies within a guarded compound a short distance from the village of Vida Largo. Is it a younger member of Hitler's inner circle, one of his twin nephews, or possibly a son mothered by his niece?
