In an alternative world where the Nazis won World War II, Germany has corralled all European countries into a single state called "Germania", and continues fighting against the Soviet Union. It is now 1964 and Germany's war crimes against the Jews have so far been kept a massive secret. Germany believes that an alliance with the United States would finally beat the Soviet war machine. As his 75th birthday comes toward him, Adolf Hitler wants to discuss a peace treaty with U.S. President Joseph Kennedy. An S.S. homicide detective and an American journalist stumble into a plot to destroy all evidence of the genocide; evidence that could destroy the peace process with America and evidence that Nazi and S.S. leaders will stop at nothing to keep hidden.
