12 Most Disturbing Moments From Prey For The Devil Ranked

Sister Ann has been battling the same demon her entire life. The reason for this is because the demon recognizes that Ann is one of God's holy warriors and wants to take her down, resulting in one fewer vessel for absolute good existing in the world. Whenever the demon confronts her it says, "Let me in!" In the opening scene of the film, it was assumed her mother meant, "Let me into your room," but what the demon is actually saying is "Let me into your soul."

In the third act, Ann realizes the only way to free Natalie is to let the demon in. She does this, and we watch as she falls to the floor and writhes in pain as her eyes go black and her lips dry. She then floats into the air, being bent nearly in half. This image can be a visual metaphor for the kind of pain human beings suffer when battling their own personal demons (mental health, addiction, etc.), and you feel the agony she must be going through.

Finally, she flings herself into a fountain of holy water as the words of her mother (and others she's met on her journey) ring in her head. The message is clear: Only by letting go of your pain can you be free. It's disturbing because although this story is about the supernatural, the struggle to find peace is painful.
