Really unique movie made in United States in 1977 year. I will grant that my expectations were very low before seeing it. Before you read this description and before I spoil you the storyline, watch the full movie, I highly recommend it. At all, Action can boast of one of the biggest numbers of good movies. Here the most important layer of the film is not the storyline, improbable scenes are just the biggest force of the film. Extremely impressive, it's the movie with the greatest conversations ever.
