After the murder of a liberal polititian (Yves Montand) in Greece a investigator (Jean-Louis Trintignant) for the prosecution starts hitting walls in his investigation. On the other side of these walls are high ranking officials within the government and army that not only are trying to hide their involvement in the murder but the also the murder itself.
The film is based on the fact that on May 22nd in 1963, in Greece, , Gregorios Lambrakis an deputy in the opposition party was fatally injured in a “traffic accident”. The event smelled of injustice and a investigator was assigned to affirm the accident but he discovered that Lambrakis was infact assasinated by a right-wing organization. Officials within the government and army were implicated but aquitted while the ones who carried out the murder were trialed and sentenced.
The film was a world wide hit which was unusual for a such a political film. It was also nominated at the Oscars for best film, best director and best script and won for editing and best foreign film.
