Nothing happened in this movie.
There was legitimately no plot, story structure, or anything else resembling what most films are normally supposed to contain.
If anyone says that "that's because it's a torture-porn" I will yet again have to strongly disagree. There was only one scene that contained even the slightest bit of "torturepornish" attributes (note: they hacked up and edited this scene through every advertisement/ trailer for this film and even played it at the beginning JUST to make you think there was more to it than there actually was).
I see no redeeming qualities to this whatsoever.
Nothing happened.
