World War II has begun and millions are dying because of Hitler's madness. Under St. Peter's Basilica there is an archaeological dig to find the tomb of the holy founder of the Church, but Pius XII exploits this place for secret meetings with the German anti-Nazi resistance. Pacelli obtained information that could change the course of the war, but the Allies did not trust it and Hitler took advantage of this by conquering France. The whole of Europe is under the control of Hitler who decides to settle the Jewish question once and for all.
Initially the Germans think of a mass deportation to Madagascar, but when they realise that this plan is unfeasible because it involves moving millions of people, Hitler decides to apply the Final Solution, sending the Jews to their death in concentration camps. What can Pius do to counter this madness? And why does he not denounce it publicly?
