Reverence (2019)

If you look into the face of evil, evil's going to look right back at you. A woman is found by a church taken to hospital for treatment, she is possessed by a dark unholy entity set on attaching itself to its newest devoted victim. Introducing the nun - "And no wonder, for even Satan disguises himself as an angel of light." 2 Corinthians 11:14 - welcome to the alter, the Nun awaits but don't look her in the eye.
