Possession.

In a cabin in the woods, a nun discovers an ancient text that releases a love demon. Possessed by the incubus, the nun is pulled towards the pleasures of her flesh. The Madonna and whore battle within her and, as her pleasure grows, the whore looks to win out. But the difference between purity and depravity is a myth, and her body’s rapture brings the nun closer to God than all the prayers could in the world.
