The quiet town of Pedraza is shaken by the birth of a mysterious child. Local vet Elena and Mayor Paco investigate the incident and begin to uncover the troubling past of their newly appointed priest, Father Vergara (Eduard Fernández) – and the significance of a curious coin he has in his possession.

Father Vergara leaves for Rome to face his painful past. He requests a meeting with the Pope, but he discovers that Santoro is waiting for him too. Meanwhile in Pedraza, someone is about to return from the dead.

After mysteriously disappearing two years ago, Elena’s husband miraculously returns. In Rome, Santoro tries to recruit Vergara, offering him unimaginable power…

Vergara flees from Santoro and hides among soldiers and war hospitals in Syria. Elena follows Roque to Paris, but is terrified when the coin finds its way back to her. In Pedraza, Paco is about to resign when a sinister new priest arrives.
