Nurse Janelle Clarke is thrilled to begin her dream job as an operating room nurse and settle into a new life with her best friend in Briar-hallow, VA. But when she starts, her position at Saint Brigid Mercy Medical, a mysterious hospital run by nuns, she quickly realizes something is not right. Her growing attraction to the handsome surgeon Dr. Damien Cross, blurs the lines between admiration and obsession. Yet Janelle cannot tell if her thoughts are her own, or if something darker is taking hold of her. Her secret confessionals offer no peace, and as halloween approaches, the hospital’s unsettling energy intensifies. The nuns begin to act strangely, her dreams grow more vivid, and the forbidden North Wing calls to her like a siren in the dark. Only Sister Magdalene seems to keep her grounded, or so Janelle believes. On Halloween night, beneath the light of the harvest moon, Janelle must decide whether to surrender to temptation, or fight for her sanity, her friends, and her soul.
