Jacqueline Byers portrays Sister Ann, a young woman grappling with a difficult past involving her mother’s schizophrenia, which fuels her desire to become a nun and assist those struggling with mental illness. She works as a nurse at a church-affiliated hospital where the Catholic Church—guided by Fr. Quinn (Colin Salmon) and psychiatrist Dr. Peters (Virginia Madsen)—combines religious practices with scientific approaches in their patient care. Fr. Quinn oversees an exorcism training program, which draws Sister Ann’s attention. Her abilities are first put to the test when she attempts to help a young girl, Natalie (Posy Taylor), who seems to be possessed; however, this encounter unexpectedly unleashes numerous demons, some of whom have a personal connection to Ann. The narrative itself isn't entirely without merit, but the acting and overall production quality feel underwhelming. While there are occasional effective jump scares, the story’s believability diminishes as it progresses. The writing awkwardly mixes religious texts with everyday language, and the resolution feels predictable and unoriginal. It gives the impression of a short story that has been expanded beyond its natural length, perhaps better suited to a brief television drama like "Tales of the Unexpected" rather than being stretched out with extended views of the attractive building where she works and an abundance of rain. I watched it tonight in a cinema holding one hundred seats, and I was not shocked to find myself the only audience member—it’s genuinely disappointing.
