Beyond the synopsis there really isn't anything else to this movie. What you read is what you get, that's the entire plot, there's no real spoilers or even anything to spoil at all. This is a movie that is a good 80% exposition without dialogue or plot development, you're just watching them move around or stare off into space. It also bounces around a little bit at times just to keep you guessing if something is actually happening or imagined...but it doesn't really matter because nothing is ever actually explained because there's no narrative or plot.
It's not a good movie, the acting is hard to judge because you don't really know what they're aiming for, and honestly it just doesn't make much sense overall since nothing is explained. The cinematography is fantastic, the cast looks great, but there's no real acting or story to see here. I just felt it seemed very pointless by the end.
