It's the mid-'50s. The economic miracle makes Germany less interested in acknowledging its recent atrocities. Fritz Bauer persists in his pursuit of justice against the Third Reich. Bauer one day receives a letter from Argentina from a man who believes his daughter is dating Adolph Eichmann's son. In search of an alliance with Mossad, the Israeli secret service, Bauer travels to Jerusalem, enthused by the promising prospect. This is treason, yet it is the only way Bauer can serve his nation.
