A couple goes on a camping trip somewhere in the woods.
For the first half hour or so they just do that.
Walking around and talking about some boring stuff.
Sometimes the woman has some visions of herself lying on a stretcher.
What??? Why???
Well at least the nature photography is quite nice.
Then they put up their tent, talk a lot of lengthy nonsense around the campfire and go to sleep when the woman has more of these stupid and boring "visions"
Then some foggy wood-creature-thingy hunts them through the woods.
Why??? What???
It could have just surprised them while they were sleeping in their tent - but who knows - perhaps the creature-thingy is also into wandering through the woods?
It is day all of a sudden, the couple is wandering through the woods again, with the creature-thingy never catching up to them, the woman has more and more of these boring visions, and so on.
Then they meet some crazy hunter guy, take shelter in his cave and now sit down there in that cave, talking nonsense for a long time while the woman has more visions.
Sounds all veeeery boring and veeery stupid?
Yes, it is.
I'll spare you the even more boring and stupid details of how it all ends but anyway most of it consists of more and more of these visions the woman has.
And they get longer and longer and longer and even more nonsensical.
And that is basically the whole boring and stupid movie.
At no point whatsoever does it get even mildly interesting, let alone suspenseful, thrilling or entertaining.
If you don't know how to tell a good story, just show some nice nature pictures and a woman with some stupid visions in the woods.
Ohhhhh....facepalm!
