A Clockwork Orange (1971)

"A Clockwork Orange" paints a horror empire by embroidering the horror and fear that a gang of violent teenagers spreads around them. The leader of the gang, Alex is caught and detained when things get out of hand. But he is not jailed; his punishment would be to be used as a guinea pig for a violence experiment. This experiment is aimed at revealing the relationship between human beings and the concept of violence, but the experiment itself is just as contrary to human nature.
