It's 1944, and the quaint Midwest farm town of Russell, Kansas, is hiding a secret that could turn the tide for Hitler and the Third Reich in Europe.
Blending among the small community of 2nd and 3rd generation German-American residents are two Nazi spies, Andreas and Peter Othmer. The siblings have been hand-selected by Germany's military intelligence service (Abwehr) to secretly document B-29 flight patterns from nearby Walker Air Force Base.
As the Allies advance eastward across Europe, the Nazi regime collapses, and with it, so does the brother's relationship, leading to a shocking truth, concealed by the town's most powerful man with strong ties to the White House.
Decades after the war, elements of the secret are uncovered, and two lifelong friends race to piece together the remaining clues, desperate to expose the dark truth before it's too late.
