They've been releasing strange teasers on the neon RU-vid channel names like "remember to say your prayers" "we've been waiting for her" "Every year there is another." "You've got the teeth of the hydra upon you." With no credits of the movie in title description like movies usually do.
That's a lot to unpack. This is not a horror, I don't think. It's a disturbing psychological thriller. And the most disturbing I have seen in awhile. Atleast that trailer. That was wild.
