Armed only with a dentist's letter, her notes, and the determination to finish her father's book, Emily Ashcroft heads to Berlin. She is joined by a Russian museum curator, an American architect, and a Mossad agent, posing as a reporter. Together they uncover what may be the greatest hoax ever perpetrated – the faked death of Hitler and the plot to return the Nazi Party to power.
