The Day of the Lord

Former Catholic priest Menéndez is released from prison after serving time for his past actions. His experience has left him heavy with guilt and memories that haunt him daily.

Menéndez is plagued by dreams of a boy who died during an exorcism while under his care. He also frequently dreams of the boy's mother, Marisa, as he grapples with his complicated feelings toward her.

Marisa visits Menéndez regularly and provides him with emotional support, despite the tragic past. Her visits serve as a reminder of his guilt but also offer moments of comfort without blame.

A friend from prison, Sebas, reaches out to Menéndez, convinced that his daughter Raquel may be possessed. Though hesitant, Menéndez ultimately agrees to meet Raquel, finding himself drawn into her turbulent life.

Upon meeting, Raquel adamantly denies her father's claims of possession, engaging in provocative banter with Menéndez. He finds himself torn between attraction to her rebellious spirit and his disapproval of her actions.

In a series of unsettling phone calls, Menéndez appears to engage with a mysterious caller whom he addresses as God. These conversations challenge his faith and force him to confront his inner demons.

As Menéndez continues to interact with Raquel, he begins to consider the possibility of her possession. This shift in belief leads him to invite Sebas to assist in confronting the spiritual crisis together.

Menéndez and Sebas embark on a desperate attempt to perform an exorcism on Raquel. Their methods quickly become extreme, veering into dark territories as they resort to torturing her for information.

During the exorcism, Sebas succumbs to despair, embracing Raquel and apologizing for their cruel actions. This moment of vulnerability somehow triggers a dramatic manifestation of the demon within Raquel.

In the chaos that ensues, Menéndez manages to escape momentarily while Raquel is restrained again. This escape signifies a turning point as they prepare for a renewed effort in their exorcism.

As they continue the exorcism, Menéndez and Sebas force the demon to manifest physically. To Menéndez's horror, the entity mirrors the boy who had died in the earlier exorcism, deepening his traumas.

Using a makeshift cross, Menéndez confronts the manifestation of the demon. With a fierce resolve, he ultimately manages to defeat it, leading to a significant moment of triumph in the climax of their struggle.

With the demon defeated, a grateful Sebas and Raquel leave Menéndez, expressing their gratitude for his help. Despite this victory, the shadows of Menéndez's past continue to linger over him.

After the exorcism, Menéndez reports his triumph during a call to the mysterious figure. However, he is confronted with the unsettling reality that the phone line is dead, leaving him in a state of uncertainty.

As Menéndez relays his victory, a ghost-like, nun figure glides towards him. This chilling apparition leaves his fate ambiguous, suggesting that the battle between light and dark may not yet be over.
