A group of friends enters an escape room and everything goes wrong in the first moments. Three of them are attacked by a demon, and the rest commit themselves to getting them back. An exorcist priest appears and provides an ancient pendant — the thing that gives the group any real ability to fight what is coming. What they discover next makes the escape room incident look minor: a hooded figure has been watching them and claims to be searching for fragments of a dark amulet that are apparently in their possession. Collecting the fragments before the hooded figure can reach them is what stands between the group and the return of a very powerful ancient evil.
