The movie is about a 24 hour period in the life of an aggressive truck driver and his assistant. The interesting thing about this movie is that there is no pathway plot or end goal for the hero to reach, it is just a 24 hour slice view of his life, which make the movie very unique and special as I have never seen this idea in a movie before. But that doesn't necessarily make a movie great on its own, what increases the greatness of this movie is that it is very open to interpretations (as a real cinema should be), it doesn't give you any direct (or indirect) answers to your questions, leaving it entirely up to your personal interpretation which is amazing and I never had that in a movie before and I have watched over a thousand movie.
