The Devil's Doorway (2018)

In October 1960, a Vatican bishop sent two priests to a Magdalene Asylum in Ireland in response to a letter claiming a statue of the Virgin Mary in the asylum chapel bled from the eyes. Of the two, Father Thomas Riley is the older and jaded miracle investigator who has seen too many frauds, while the younger Father John Thornton is enthusiastic about the assignment, and believes they will find a genuine miracle.

Initially, the asylum's authoritarian Mother Superior tries to discredit the letter (sent anonymously from her hospice) by reminding the priests that "they are not all good girls in this home." She makes it clear the priests are not welcome, treats them grudgingly, and installs them in separate accommodations.

Father John sets up his (16 mm cameras) in the chapel, pointed at the statue. As the blood has dried up, Father Thomas cannot sample and analyse it, so they will have to wait for another occurrence. Meanwhile, Father John interviews some of the women in the asylum, and soon discovers they have no access to the chapel and are subjected to cruel punishments to ensure discipline. They are also exploited for labour, responsible for both keeping the asylum clean and running the local laundry business. The abuse is discussed with the Reverend Mother. Despite being unhappy that the priests have to document all their activities and conversations, she defiantly stands her ground, claiming her role is to "clean up" many other Churches' dirty secrets, including babies whose fathers are fathers.

For two nights, Father John is awakened at 3 a.m. by strange sounds and apparent visions of children playing in the hallways. He informs Thomas, who denies hearing anything. They ascertain that there are no children in the asylum; the children's wing has been closed since the war. Father Thomas is convinced that a con man is behind these strange occurrences. However, on the third day, all the statues of the Virgin Mary in the asylum bleed at the same time. A brief analyses reveals that the samples are of type O-negative, and come from a pregnant woman. Father Thomas compares the samples with the blood of the inmates and the nuns, but finds no match.

A nun privately admitted that she was the one sending the anonymous letter. She informs Father Thomas of a young pregnant woman named Kathleen O'Brien being held in a secret room in the basement, and recites, "If your eye makes you sin, pluck it out and throw it away".

Despite the Mother Superior's stern objections, Father Thomas insists on seeing Kathleen. She is emaciated, scarred and chained in a filthy room. A local doctor confirms that the girl is a virgin but is also pregnant. Attempts to move Kathleen beyond her room result in violent attacks and manifestations of apparent demonic possession. Father Thomas interviews Kathleen, who claims to be possessed by an unknown entity.

After a series of supernatural phenomena, the two priests discover a room with evidence of satanic cult activities, including a Black Mass. Father Thomas reveals to Father John that he was an orphan, and speculates he may have been born in this asylum. Kathleen cryptically implies that babies were killed in the asylum. Kathleen goes into labor and dies in childbirth.

More supernatural phenomena ensues, and the two priests find a nun murdered, her eyes gouged out. Then get to a network of tunnels containing skeletons of small children. The two become disoriented and are separated when a nun attacks them. Father John is killed by the nun.

After taping a confessional, Father Thomas finds a satanic altar. A group of nuns who form a coven and are performing a ritual. A possessed Mother Superior says, "Welcome home, Thomas" and suddenly attacks him. After Father Thomas falls, Mother Superior is heard shushing a crying baby.
