I am not sure how this film came on my watchlist, but I may have been looking for films with Frances MacDormand. Besides her, we also have Willem Dafoe and Gene Hackman.
Dafoe is a young FBI agent who is sent to Mississippi with his senior partner Hackman to investigate the disappearance of three young activists. They come to a small community in which the Ku Klux Klan reigns supreme and the FBI stirring up the status quo leads to a massive increase of violence against the black half of the population.
Parker shows the hatred of the whites towards the black and the powerlessness of the blacks in a disturbing way. Unbelievable that there are people who think and act in such a way. Of course towards the end all major clan-members are put to trial and convicted, but this was not exactly an easy process.
A very good film about a very black page in American history.
