The Ultimate Fighter

Series premiere. The quiet town of Pedraza is shaken by the unsettling birth of a mysterious child. As local vet Elena and Mayor Paco form a tenuous alliance to investigate the incident, they begin to unravel the troubling past of their recently appointed priest, Father Vergara -- and the significance of a curious coin in his possession.

Elena confronts a seemingly skeptical Father Vergara over his connection to the sudden disappearance of a neighborhood girl. As untimely deaths befall the town, marquess Roque presents Elena with an enticing job offer, and Merche urges Paco to keep his distance from the mayhem.

Elena and Paco learn the ancient origins of a book in the haunting reflection of a local couple's mirror. When Father Vergara spends the night investigating the mirror's trickery, he risks getting swept into a deathly portal.

Old acquaintances Sandro and Santoro delight in Father Vergara's return to Rome. Meanwhile, in Pedraza, the townspeople struggle to make amends with an embittered Elena as Paco fights to keep her close.

The village is further undone by Mario's return, sending Paco on an urgent quest for answers. As Sandro and Santoro each appeal to Father Vergara's better nature, the hunt for the final coin puts Elena in greater danger than ever before.

While Father Vergara seeks refuge from Santoro in Aleppo, he ventures into the dream world to contact Elena, who's eloped to Paris with Roque. Meanwhile, in Pedraza, marital tensions between Paco and Merche reach a boiling point, and federal agents descend on the town to take matters into their own hands.

Angel arrives in Pedraza with a sinister plan and enlists Merche to do his bidding. As an ominous fog fills the streets, the townspeople grow increasingly restless. Meanwhile, Laguna finds himself at odds with the federal agents, Paco falls mysteriously ill, and Elena and Father Vergara rush to get home before it's too late.

Season finale. Elena, Paco and Father Vergara take shelter in an abandoned wine cellar as they fight to free the people of the Pedraza from the spell of the Black Circle. While Angel prepares the town for Santoro's fateful arrival, Merche's allegiances remain to be seen.
