There are lots of little clues/hints about this in the movie—many little things have a meaning—but we're not very "tight" with it, because we are hoping people will have their own ideas about the story, and make a new version of the movie. In this way (and others) we tie the story of the movie with the "open movie" idea."
Bassam Kurdali, the director, explained the plot of the film:"The story is very simple—I'm not sure you can call it a complete story even—It is about how people create ideas/stories/fictions/social realities and communicate them or impose them on others. Thus Proog has created (in his head) the concept of a special place/machine, that he tries to "show" to Emo.
