After a personal tragedy, Sarah joins her friends on a caving expedition in the Appalachian Mountains. But when a rockfall traps them deep underground, their adventure turns into a nightmare. As they search for a way out, the group discovers they are not alone—lurking in the darkness are savage, cave-dwelling creatures. With rising tension and dwindling trust, the women must fight to survive against both the predators and each other.

I would survive this because there is no way I would ever have gone into that cave in the first place. Also this movie is criminally underrated

i can see why people love this, it has some great aspects to it but that first hour was quite literally the most unenjoyable and longest hour ever.
as if you needed another reason to not go spelunking.

Haunting and thrilling. I felt super claustrophobic watching this shit. Great usage of jumpscares, I really didn’t expect quite a few of them to be honest. One of the best horror movies made on a budget.
