What Happens in Who Killed the Prosecutor and Why?: Full Plot Summary

The whole story of Who Killed the Prosecutor and Why? (1972) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

On a sunlit beach, a young photographer named Carlo Lou Castel wraps a photoshoot with his model girlfriend Olga Beba Lončar and the pair share a quiet moment before they move on with their day. Not far away, a grim scene unfolds: two men haul a murdered man to a car, bump the vehicle, and set it on fire to stage the death as an accidental crash. Carlo and Olga witness the whole brutal act, Carlo documenting every crucial beat with his camera, catching the flicker of fear and the precision of the staging in frame after frame.

The victim is Giuseppe Anchisi, a high-ranking prosecutor, and the case pulls the string of a larger, murkier conspiracy. Inspector Vezzi [Adolfo Celi] is under mounting pressure to crack the mystery, and he tries to keep the press at bay by steering the narrative with a lie that the mob is the suspect. Carlo brings the photographs to his boss, Ivan Smirkov—better known as “Uncle Fifi” [Massimo Serato]—a paraplegic studio director who lives for sensational stories, and who believes there’s serious money to be made from the evidence.

Carlo then approaches Don Salvatore Aniello [Fortunato Arena], a mafia boss, with the idea that the exonerating photos could clear his name—but the demand for 20 million lire shocks the room, and Don Salvatore laughs off the offer. Meanwhile, one of the killers, Garrù [Domenico Maggio], is shot dead by his accomplice outside a nightclub, injecting a fresh note of danger into the already tense chain of events. Unfazed, Carlo turns to a newspaper he once worked with, pressing for the same payoff, and the editor, Mauri [Antonio La Raina], hesitates, aware of the risks that publishing the photos could unleash.

A anonymous call signals a ransom, and the paper sends Roversi [Carlo Landa] to retrieve the incriminating material. The killer strikes first, stabbing Roversi to steal the photographs, but the loot isn’t with him—it's a trap that the killer escapes. The fallout hits close to home as Inspector Vezzi fumes at the paper, Carlo, and Uncle Fifi for delaying the investigation just as the killer shifts focus toward them.

Carlo and Olga are forced into hiding, but the danger catches up with Uncle Fifi when the killer strangles him. Olga endures a brutal assault as the intruder searches for Carlo, and although Carlo rushes to intervene when he hears her cries from the hospital, Olga dies from her injuries shortly afterward.

With the net closing in, Carlo leans on Vezzi, who decides to use him as bait. The staged meeting goes awry when the would-be killer appears to shoot Carlo, but the bullet is blocked by a pane of protective glass. When the room lights swing onto the suspect, the killer is unmasked as Mauri [Antonio La Raina], who is cornered and arrested. Mauri’s disclosure reveals a web of collaboration with Garrù and a darker motive: he killed Anchisi to halt the investigation’s momentum. The confession ties together the blackmail, the killings, and the cover-ups, and Carlo ultimately finds a measure of absolution for his role in navigating the perilous press-and-police maelstrom.

In the end, truth, money, and danger collide, leaving Carlo to reckon with the costs of bearing witness in a case where power and crime are deeply intertwined, and where the price of justice may be paid in lives and reputations rather than in headlines.

Who Killed the Prosecutor and Why? Plot Explained: Your Questions Answered

The questions people ask most about Who Killed the Prosecutor and Why? (1972): what happens in the confusing scenes, why the characters do what they do, the twists, hidden details and what the ending means. Each answer contains spoilers.

Q1

Why was prosecutor Anchisi killed?

Mauri, the newspaper editor, orchestrated Anchisi's murder to halt the investigation before it exposed his drug operation. Working with Garrù, one of the actual killers, Mauri staged the hit-and-run to make the killing look like an accident. By eliminating the prosecutor, Mauri believed he could stop the inquiry into his criminal activities before it reached him.

Foreshadowing: Earlier, Inspector Vezzi notes the unusual speed of the case being closed as an accident, hinting at powerful interests benefiting from the prosecutor's death.

  • anchisi murder
  • prosecutor killed
  • mauri drug dealer
  • why anchisi died
Q2

Who was the black-gloved killer?

The killer was Mauri, the newspaper editor himself. Throughout the film, Mauri posed as a reluctant publisher while actually orchestrating the elimination of everyone connected to the incriminating photographs. He killed Garrù outside the nightclub, stabbed Roversi during the ransom drop, strangled Uncle Fifi, and attacked Olga - all to keep his drug operation hidden.

Foreshadowing: Mauri hesitates to publish the photos despite the potential scoop, and he is the one who organizes the ransom drop - revealing his desperation to control the evidence.

  • killer identity
  • mauri killer
  • who killed
  • assassin revealed
Q3

Why did Don Salvatore reject Carlo's offer?

Don Salvatore laughed at Carlo's demand for 20 million lire because the amount was excessively high and the mafia boss saw the young photographer as overstepping. More importantly, Don Salvatore had no intention of paying for evidence that could implicate his own organization. The rejection signaled that Carlo's attempt to profit from the photos would not work through criminal channels.

Foreshadowing: Earlier, Inspector Vezzi manipulates the press by suggesting mob involvement, establishing that the mafia already has reason to want the case closed quickly.

  • mafia refuse
  • 20 million lire
  • carlo bribe
  • don salvatore
Q4

Why was Carlo targeted by the killer?

Carlo became the killer's primary target because he possessed the photographs documenting the staged murder. These photos threatened to expose Mauri's drug operation and the conspiracy surrounding Anchisi's death. By eliminating Carlo, Mauri could recover or destroy the evidence and silence the only witness with visual proof of the crime.

Foreshadowing: Carlo's decision to photograph everything and then attempt to sell the photos directly places him in the crosshairs of those who need the truth suppressed.

  • carlo targeted
  • why carlo danger
  • photographer threat
  • killer motive
Q5

What triggered the chain of killings?

The killings began the moment Carlo photographed the staged murder and decided to use the evidence for profit. His attempts to blackmail both the mafia and the newspaper created a chain reaction - Mauri, fearing exposure of his drug operation, systematically eliminated everyone who knew about the photos or could connect them to Anchisi's murder.

Foreshadowing: The very first scene establishes Carlo as a witness with a camera, setting in motion every subsequent violent event.

  • chain reaction
  • killings cause
  • photo evidence danger
  • blackmail consequences
Q6

Why did Inspector Vezzi use Carlo as bait?

Vezzi used Carlo as bait because conventional police work had failed to identify the killer. By staging a meeting where Carlo would appear vulnerable, Vezzi created an opportunity for the killer to reveal themselves. The plan worked - when the killer fired, the bullet struck protective glass instead of Carlo, and the sudden lighting revealed Mauri as the attacker.

Foreshadowing: Vezzi's earlier frustration at the delays and his redirecting of blame toward Carlo and the press establish his willingness to take desperate measures.

  • vezzi plan
  • carlo bait
  • trap killer
  • police sting operation
Q7

How did police identify Mauri as the killer?

Mauri was identified during the staged meeting trap. Carlo waited as bait while police hid nearby. When the killer arrived and fired, the bullet struck a pane of protective glass. When the room lights were turned on, the killer's mask fell and Mauri was revealed. He was immediately arrested and later confessed to killing Anchisi to protect his drug operation.

Foreshadowing: The ransom drop scene shows the killer knew details only someone with inside knowledge would have, hinting the threat came from within the newspaper itself.

  • mauri arrested
  • killer revealed
  • how identified
  • unmasking scene
Q8

Why was Olga attacked and killed?

Olga was attacked because the killer was searching for Carlo. When Carlo and Olga went into hiding, the killer tracked them down. Finding only Olga, the attacker assaulted her trying to force her to reveal Carlo's location. Olga died from her injuries in the hospital, marking the film's devastating personal cost.

Foreshadowing: The earlier attack on Uncle Fifi establishes that the killer will eliminate anyone close to Carlo to get what he wants.

  • olga death
  • why olga killed
  • carlo girlfriend
  • attack consequence
Q9

Why was Uncle Fifi killed?

Uncle Fifi was killed because he was Carlo's boss and the person who first received the incriminating photographs. As the intermediary who helped plan how to monetize the evidence, Uncle Fifi knew about the photos and could potentially cooperate with police or reveal information. The killer strangled him to eliminate this loose end.

Foreshadowing: The timeline shows Uncle Fifi's role in encouraging Carlo to exploit the photos, making him a target once the killer began systematically removing everyone connected to the evidence.

  • uncle fifi death
  • ivan smirkov killed
  • why intermediary killed
Q10

What happened to the incriminating photographs?

The photographs changed hands multiple times throughout the film. Carlo first gave them to Uncle Fifi, then tried selling them to the mafia and newspaper. During the ransom drop, the killer stabbed Roversi expecting to find the photos, but they weren't with him - it was a trap. The photos ultimately served their purpose in exposing the conspiracy when Mauri was unmasked.

Foreshadowing: The failed ransom drop, where the killer finds nothing, demonstrates that Carlo had learned to protect the evidence by keeping it hidden.

  • photos evidence
  • what happened to photos
  • carlo photographs
  • proof destroyed
Q11

Why did Mauri hire Garrù to kill the prosecutor?

Mauri hired Garrù to kill prosecutor Anchisi because the investigation threatened to expose Mauri's drug operation. Rather than risk a lengthy prosecution that could reveal his criminal network, Mauri arranged for the prosecutor's death and staged it as an accident. Garrù was the hired killer who carried out the actual murder while Mauri coordinated from within the newspaper.

Foreshadowing: The film reveals Mauri's drug operation only at the end, but his hesitation about publishing and his quick action to silence threats provide subtle early hints.

  • garrù hired
  • who hired killer
  • prosecutor murder contract
  • mauri motives
