According to documents that were declassified by the FBI in 2014, Adolf Hitler may have survived World War II and fled to South America following the fall of Nazi Germany. In this series a team of investigators led by 21-year CIA veteran Bob Baer and war crimes investigator John Cencich undertakes a definitive search with the goal of finding out whether the notorious dictator actually survived the war and pulled off one of history’s greatest disappearing acts. In Season 3 Bob Baer recruits one of the world's most foremost terrorist targeting officers, Nada Bakos. Enacting a new hunting strategy so effective it led to the capture of Osama bin Laden, the team uncovers two planned escape routes for Hitler out of Germany: one to the north and one south. Along the southern route, Tim and James discover a vast tunnel system under Hitler's home. Up north, Lenny and Gerrard investigate a massive Nazi compound hiding under the perfect cover.
