Better known as INVESTIGATION OF A CITIZEN ABOVE SUSPICION, this Oscar-winning political drama stars Gian Maria Volonte as the citizen of the title, an unnamed police inspector. The story finds the inspector calmly cutting his mistress' throat, then planting evidence that will clear him of accusation -- and attempting to evade arrest by virtue of his "clean" public image. Elio Petri's own anti-establishment stance was never more pronounced than in this film, where the truth is whatever the ruling class chooses to acknowledge. The original Italian title of INVESTIGATION OF A CITIZEN ABOVE SUSPICION was INDAGINE SU UN CITTADINO AL DI SOPRA DI OGNA SOSPETTO.
