The film is a sequel to the 2008 film "The Haunting of Molly Hartley". It was released on Digital HD on October 9, 2015, and on Blu-ray on October 20, 2015. After causing a botched exorcism that resulted in the death of a fellow priest and a pregnant woman, Father John Barrow (Devon Sawa) is committed to a Catholic mental asylum. Chaplain Henry Davies (Peter MacNeill) informs him that the Vatican has revoked his status as a priest. Meanwhile, Molly Hartley (Sarah Lind), the morning after celebrating both her twenty-fourth birthday and becoming the youngest partner in her firm, is arrested after police inspecting her home after a noise complaint finds the corpses of the two friends she engaged in a threesome with the night before. While interrogating Molly, she hears strange noises before she begins to have a deeper voice and refers to herself as "we". She is sent to the same mental asylum for psychiatric evaluation under Dr. Laurie Hawthorn (Gina Holden), but her condition worsens after an insect-like creature enters her body. Hawthorn looks through Molly's past records and diagnoses Molly's symptoms as her subconscious fulfilling a claim she told her high school guidance counselor that she was claimed by the devil on her eighteenth birthday (which explains the sudden change from an average student to becoming academically successful) and describes it as an incubation or pregnancy for six years, six months, and six days. However, after supernatural occurrences happen around Molly, who is forcibly bound to her bed in solitary, Dr. Hawthorn begins to believe in demonic possession. With limited options, she asks Barrow to perform the exorcism in exchange for signing his release forms. Though he initially refuses, after the suicide of an asylum employee, supernatural occurrences, and seeing Molly for himself, he visits Davies, who encourages him to help Molly, handing him his clerical attire and the items he needs to perform the exorcism. On the last day of incubation, before going to Molly's room, Barrow sees several people clad in black standing outside. Barrow manages to perform the exorcism, trapping several insects that come out of Molly's mouth in a special box, which he keeps in a container filled with holy water. Molly recuperates in a shared room, thanking Barrow for saving her. Dr. Hawthorn signs his release papers, but as Father Barrow walks out the asylum, patients and orderlies stare at him. Barrow returns the container to Davies, who places it in his basement for safekeeping.
