The Exorcism of God (2021)

In 2003, Father Peter Williams, an American priest serving in Mexico, is called to perform an exorcism on a young woman named Magali Velasquez. During the ritual, Peter appears to lose control, and the demon momentarily overpowers him. However, the full extent of what transpired is left ambiguous. Despite this, Peter continues his priesthood, dedicating himself to charitable work in a small Mexican town.

Eighteen years later, supernatural disturbances begin to unfold. A deadly illness spreads among the town's children, and a young woman named Esperanza, incarcerated in a local prison, begins exhibiting violent signs of demonic possession. Peter is called to perform an exorcism, but the encounter unsettles him. His past seems to be catching up with him. Shortly after, Magali informs Peter that Esperanza is her biological daughter, and she urges him to save her at all costs.

Recognizing that he cannot handle the situation alone, Peter seeks assistance from Father Michael Lewis, an experienced exorcist. As they prepare to perform the ritual, they discover that the demon's influence has already spread, possessing multiple inmates inside the prison. The priests are overpowered and forced to lock themselves in a room. During their desperate attempt to regain control, Father Lewis questions why Peter's prayers seem ineffective and whether he is harboring any sins. Peter confesses that during the failed exorcism eighteen years ago, he was not only possessed but was seduced by the demon inhabiting Magali. Under its influence, he engaged in intercourse with her, leading to Esperanza's birth. The realization shakes Father Lewis, who then admits his own dark secret—he never actually defeated the demon Balban in the past but instead made a deal with it.

Before Father Lewis can do more, he is fatally wounded by one of the possessed inmates. With his dying breath, he warns Peter to never make a deal with Balban. Determined to atone for his past sins, Peter records a video confession and sends it to the Church authorities, hoping to absolve himself. However, before he can act further, the possessed inmates attack him, knocking him unconscious.

Peter awakens to find himself restrained, surrounded by the possessed inmates and Esperanza, now fully under Balban's control. The demon and its followers begin a ritual intended to sever Peter's connection with God. As he attempts to exorcise the demon from Esperanza, Balban forces him to witness children in the church dying one by one as a consequence of his resistance. The demon then presents Peter with a devastating choice: he can either save the children, save his daughter, or relinquish his divine connection.

Peter ultimately chooses to renounce his faith, allowing himself to be possessed by Balban. As the demon takes full control, it declares victory. Now in a fully possessed state, Peter is last seen wearing a twisted, demonic grin, his soul seemingly lost.
