If your looking for a short thriller movie, i highly recommend this one.
A lil bit ogre/unrealistic with the wolves, i must say, and there are definitely other ways to climb down the thingy they were riding. If only they put much time thinking about it they could have survived but of course they are only normal people so i don't have any say on that.
And sometimes, the one who we thought won't survive, are the ones who ends up surviving.
