Religious horror is about the battle between good and evil, light and dark, and the good and the demonic.
The new Consecration trailer shows this theme and the fall into a world of darkness very well.
In the beginning of the trailer, a young woman named Grace finds out that her brother has died.
She doesn't believe the story about how her brother died, so she goes to Scotland to find out what really happened.
As the young woman finds out when she turns every corner and talks to every person.
While she's there, she notices that one of the nuns is acting strangely, almost like a child.
This nun keeps popping up and saying "Peekaboo!" and both the head priest and the Mother Superior don't seem too eager to help Grace figure out what happened.
Grace notices strange habits, like the nuns walking in a circle backwards.
