Since his rise to power, Russian President Alexander Volkov has increasingly engaged in hostile activities as he attempts to rebuild the Russian Empire. In support of his tactics, the Russian FSB has forged a Concordat dated 1939 in which the Vatican supposedly agreed to cease all opposition to the Nazi government in return for being appointed the official state religion of the Third Reich.
Planting the counterfeit in a Berlin apartment, the FSB engineer a plan to blackmail the Vatican via the son of a murdered former East German Stasi colonel. The Vatican reluctantly agrees to acquire the counterfeit to prevent it falling into the hands of the Church's enemies, sending the head of the Vatican Police, Lorenzo Rossi, to Germany to negotiate with the blackmailer. But Rossi's flight is delayed and by the time he arrives the blackmailer is dead and the Concordat has vanished.
Rossi follows a deadly trail to Paris and onto Moscow, where he meets Cathy Doherty, a CIA Agent with a passion for all things Russian. Together they set out to establish the origins of the Concordat, and its intended purpose. Armed with information provided by a CIA informant, the forger is identified. Will Rossi be able to recover the Concordat and flee Russia with his life?
