What Happens in The Professor: Full Plot Summary

The whole story of The Professor (1986) 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.

In 1963, the young man Franco, Franco Interlenghi kills a boy who had harassed his sister Rosaria, Laura del Sol, and ends up in prison. Over ten years in Poggioreale prison in Naples, he rises to become a feared and authoritative figure known as 'O Professore di Vesuviano Ben Gazzara. From his prison cell he forges a new criminal in-group, allying with Alfredo Canale Nicola Di Pinto and Pasquale Zara the “animal” to form the organization Camorra Riformata. This tight-knit cell quickly expands its reach, clashing in the 1970s with the old Camorra families and sparking the War of the Camorra that stains southern Italy through the 1970s and 1980s.

The turmoil broadens when Naples and the Campania region are struck by a devastating earthquake in 1980, intensifying the struggle over reconstruction money and power. In 1981, the Red Brigades kidnap regional assessor Mimmo Mesillo, Piero Vida (Ciro Cirillo in real life). Members of Mesillo’s Christian Democrat party seek the Professor’s intervention, fearing Mesillo’s possible disclosures. In exchange, the Professor is promised freedom on mental illness grounds and a 3 billion-lira ransom. Mesillo is freed, but is then placed in the custody of the secret services rather than the police.

The political authorities later ignore the bargain, and the Professor is moved to the high-security prison of Asinara by a decree from Italian president Sandro Pertini. This decision accelerates the disintegration of his once-loyal network as trusted men begin cooperating with the police. Rosaria, his sister, fights to stem the damage, but her efforts prove futile. In the end, Ciro is killed when his car is blown up, and his partner is dissolved in acid, a blow that drives the Professor toward a breaking point. After these events, he descends into madness, convinced that someday his men will release him.

The questions people ask most about The Professor (1986): 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 did Franco kill the boy who harassed his sister?

Franco killed the boy because the boy had been harassing his sister Rosaria. This violent act, committed in 1963 to protect his sister's honor, was the spark that led to Franco's imprisonment in Poggioreale Prison in Naples, where he would eventually transform into the feared Professor.

  • Rosaria
  • killing
  • harassment

Q2

How did Franco become known as The Professor in prison?

Over ten years (1963-1973) in Poggioreale Prison, Franco used a combination of intelligence, strategic alliances, and intimidation to rise to a position of authority among inmates. He earned the nickname 'O Professore di Vesuviano' by demonstrating leadership skills and building a loyal criminal network that would later form Camorra Riformata.

Q3

What was Camorra Riformata and why was it important?

Camorra Riformata was the criminal organization Franco founded inside Poggioreale Prison alongside Alfredo Canale and Pasquale Zara ('the animal'). It was significant because it was a prison-born network that expanded beyond cell walls, challenging old Camorra families and sparking the brutal War of the Camorra that devastated southern Italy through the 1970s and 1980s.

  • Camorra Riformata
  • Alfredo Canale
  • Pasquale Zara
  • organization

Q4

Why did the politicians break their deal with the Professor?

After the Professor helped secure Mimmo Mesillo's release from Red Brigades captivity, the politicians reneged on their promise to free him on mental illness grounds and pay the 3 billion-lira ransom. Instead, they moved him to the high-security Asinara prison by decree of President Sandro Pertini, effectively silencing him and cutting his influence.

Foreshadowing: The earlier deal between the Professor and political authorities established the corrupt bargain that made his eventual betrayal more devastating.

  • deal

  • freedom
  • Mesillo

Q5

How did the 1980 Naples earthquake affect the Camorra conflict?

The devastating 1980 earthquake in Naples and Campania intensified the struggle over reconstruction money and power among criminal factions. As resources flooded in for rebuilding, the Camorra war escalated as factions fought ruthlessly for control of these funds, consolidating power for the most ruthless groups.

Q6

Why did the Professor's organization collapse after his transfer to Asinara?

When the Professor was moved to Asinara prison in Sardinia, he was cut off from his network. His trusted men, now isolated from his leadership, began cooperating with police. This betrayal from within caused the organization to disintegrate rapidly, despite his sister Rosaria's efforts to stem the damage.

Foreshadowing: The Professor's earlier reliance on a tight-knit inner circle became a vulnerability once he was physically removed from Naples.

  • Asinara
  • network
  • collapse
  • betrayal
  • Rosaria
  • police
Q7

Why was Ciro killed and dissolved in acid?

Ciro was a trusted member of the Professor's organization who sold out to politicians, cooperating with authorities after the Professor's removal. As punishment for this betrayal, Ciro was killed by a car bomb, and his partner's woman was dissolved in acid, brutal acts demonstrating the organization reach and the consequences of disloyalty.

  • Ciro
  • betrayal
  • killing
  • acid
  • car bomb
  • punishment
Q8

Why did the Professor descend into madness?

After being betrayed by politicians, losing control of his organization, and learning of Ciro's execution and the acid dissolution, events that shattered his remaining power and loyalty, the Professor was driven to insanity. Confined in Asinara, he became convinced that someday his loyal men would release him, withdrawing into delusion as his world crumbled.

Foreshadowing: The Professor's psychological break was foreshadowed by his gradual loss of control over the very organization he built from prison.

  • Professor
  • madness
  • insanity
  • breakdown
  • confinement
  • delusion
Q9

What role did Rosaria play in the Professor's organization?

Rosaria, Franco's sister, served as a crucial ally in attempting to protect the organization after the Professor's transfer to Asinara. She fought to counteract the damage from betrayals and shield the network from collapse, though her efforts ultimately proved futile as the organization disintegrated from within.

  • Rosaria
  • sister
  • support
  • organization
  • damage control
Q10

Why was Mimmo Mesillo handed over to secret services instead of police?

After the Professor orchestrated Mesillo's release from Red Brigades captivity, the politician allies placed Mesillo directly in secret services custody rather than police custody. This move circumvented the original agreement and prevented the Professor from maintaining leverage, signaling the authorities' intent to break their deal with the criminal organization.

  • Mesillo
  • secret services
  • custody
  • police
