Its a long story so this might be kind of long: Two guys find a cave, hear a creepy scream and grinding rocks from inside, one guy goes in and comes out really scared/messed up and won't say what happened, eventually the main guy goes in and notices weird stuff, a stench appears and the two guys book ass out of the cave, both of then live in paranoia afterwards, they decide to go back and thats where it ends.
Sorry for the terrible grammar.
