小心孩子！

A boy is haunted by terrifying nightmares where a monster lurks inside the closet. To his relief, his father appears in the middle of the night helping him to face his fears. But the boy will begin to question the true nature of these apparitions, having to face the truth about his father's destiny and the evil force that threatens to consume him.

电影灵感源自上世纪20年代美国“艾玛·施密特事件”：女子艾玛被恶魔附身数十年，寻求修道院帮助后，经历了数次残酷的驱魔仪式。这也是美国历史上对“驱魔”记载最详尽的案例。电影主角是两位正在经历信仰动摇(史蒂文斯)、有着复杂过去(帕西诺)的牧师，他们必须放下分歧，通过一系列艰难而危险的驱魔仪式来拯救被附身的年轻女子。
