What Happens in The Sunday Woman: Full Plot Summary

The whole story of The Sunday Woman (1975) 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.

Inspector Santamaria, Chief of Homicide Squad, Marcello Mastroianni, is assigned to investigate the murder of the architect Garrone, Claudio Gora, a second-rate fellow living on the fringes of polite society, who has been battered to death with a stone phallus.

Anna Carla Dosio, Jacqueline Bisset, the bored wife of a businessman who is often away, brings to the police a discarded draft of a letter she planned to send to her dear friend Massimo Campi, Jean-Louis Trintignant, in which she says they must rid Garrone.

Massimo Campi, Jean-Louis Trintignant, has a secret lover, a young clerk named Lello Riviera, Aldo Reggiani, who works in the city’s planning department, and Santamaria has the young man followed.

It emerges that Garrone was acting for the widow Ines Tabusso, Lina Volonghi, who lives in a crumbling villa, along with a “simple” sister. The house sits on Turin’s renowned Hill, and if she could obtain permission to build around the villa’s surroundings, she would make a fortune.

The Inspector is warned by his boss to move with care now that rich and influential people are involved. All his suspects have motives for killing Garrone, and none have solid alibis for the time of his death. While Campi withholds cooperation, to protect his homosexuality, Anna Carla enthusiastically assists Santamaria and promises him a secret rendezvous, beginning with lunch.

Hoping to win the cooperation of Ines, Santamaria mounts a night raid to clear her property of prostitutes.

By coincidence, a Saturday morning finds all the involved at the Balon, the city’s flea market, where Riviera is to meet with the possible murderer, but he is himself killed by a stone pestle.

The culprit is Ines, who killed Garrone after he had discovered by chance that on her property there was an ancient and artistic stone used as a laundry, set under the provisions of Art Superintendence, so the Tabusso grounds were forbidden to sell; Garrone had tried to coax her into believing the interdiction would be removed if she bribed the right people.

With the case solved, Santamaria and Anna Carla are able to enjoy the private lunch they promised each other. Their quiet, sunlit afternoon ends when she must get out of bed to start packing for the family holidays.

The Sunday Woman Plot Explained: Your Questions Answered

The questions people ask most about The Sunday Woman (1975): 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 Garrone killed with a stone phallus?

The stone phallus was the murder weapon because Ines Tabusso used a similar stone object from her property. The weapon's macabre nature was meant to suggest a crime of passion, but it actually pointed to Ines, who had access to such stones on her villa grounds where ancient artistic stones were used as laundry equipment.

Foreshadowing: The unusual weapon foreshadows the later revelation that the murder originated from property disputes on Turin's Hill.

  • stone phallus
  • murder weapon
  • Garrone death
  • Turin
Q2

What was in Anna Carla's letter to Massimo Campi?

In a discarded draft letter to her friend Massimo Campi, Anna Carla wrote that they must 'rid' Garrone. This draft was discovered by her servants and brought to the police, making her an immediate suspect despite her claims she never sent it.

Foreshadowing: The letter establishes Anna Carla's potential motive and hints at the tangled relationships among Turin's elite.

  • letter
  • Massimo Campi
  • Anna Carla
  • Garrone
  • draft
Q3

Why did Ines Tabusso kill Garrone?

Ines killed Garrone after he discovered that her property contained an ancient artistic stone used for laundry, which was protected by Art Superintendence regulations. This meant the land could not be sold for development. Garrone had deceived her, suggesting that bribing officials could remove the interdiction, when in fact it was impossible to bypass.

Foreshadowing: Earlier scenes establishing Garrone's work for Ines and the property's potential value hint at this financial motive.

  • Ines Tabusso
  • Garrone
  • property
  • Art Superintendence
  • murder motive
Q4

Who killed Lello Riviera at the Balon flea market?

Ines Tabusso also killed Lello Riviera at the Balon flea market using a stone pestle. Riviera had gone to meet what he believed was the murderer, but Ines was there and killed him to prevent him from revealing her as the killer of Garrone.

Foreshadowing: The second murder mirrors the first, using another stone object from Ines's property.

  • Lello Riviera
  • Balon
  • flea market
  • second murder
  • Ines Tabusso
Q5

Why did Santamaria raid Ines Tabusso's property?

Santamaria staged a night raid to clear Ines Tabusso's property of prostitutes in hopes of winning her cooperation with the investigation. By doing her a favor and disrupting the illicit activity on her grounds, he intended to establish a rapport that would make her more willing to share information about Garrone.

Foreshadowing: The raid demonstrates Santamaria's investigative methods and foreshadows his growing involvement with the property's secrets.

  • Santamaria
  • night raid
  • Ines Tabusso
  • prostitutes
  • investigation
Q6

What did Garrone discover about Ines Tabusso's property?

Garrone discovered that on Ines Tabusso's property there was an ancient artistic stone used as laundry equipment, which was protected under Art Superintendence provisions. This discovery meant the grounds were forbidden to sell for development, destroying the financial opportunity that had motivated Ines to hire him.

Foreshadowing: This discovery directly triggered Ines's decision to kill Garrone to keep him from revealing the bad news.

  • ancient stone
  • Art Superintendence
  • property
  • building permit
  • Garrone
Q7

Why did Massimo Campi refuse to cooperate with the police?

Massimo Campi withheld cooperation to protect his homosexuality, which was socially scandalous at the time. Since his secret lover Lello Riviera was being followed by police as part of the investigation, Campi feared that disclosing their relationship would expose his sexual orientation and ruin his social position.

Foreshadowing: This secrecy creates tension throughout the film and explains why Campi becomes an unreliable witness.

  • Massimo Campi
  • homosexuality
  • police
  • cooperation
  • Lello Riviera
Q8

What is the connection between the two murders?

Both Garrone and Lello Riviera were killed by Ines Tabusso using stone objects from her property, the same type of ancient artistic stones protected by Art Superintendence that had motivated the first murder. Riviera was killed at the Balon market because he was getting close to discovering Ines as the culprit.

Foreshadowing: The similar murder weapons link both crimes to the same location and same perpetrator.

  • two murders
  • stone objects
  • Ines Tabusso
  • connection
  • Balon
Q9

Why does Anna Carla help Santamaria with the investigation?

Anna Carla assists Santamaria partly to clear her name from suspicion due to the incriminating letter, but also because she is bored with her marriage and attracted to the inspector. She promises him a secret rendezvous beginning with lunch, trading information for personal connection.

Foreshadowing: Their collaboration evolves from suspect and investigator to romantic partners.

  • Anna Carla
  • Santamaria
  • investigation
  • help
  • romance
Q10

What happens between Santamaria and Anna Carla at the end?

After the case is solved, Santamaria and Anna Carla finally enjoy the private lunch they promised each other. However, their romantic encounter is brief and transient, Anna Carla must get out of bed to start packing for family holidays, returning to her ordinary life and leaving Santamaria alone.

Foreshadowing: The ending reflects the film's cynical view of relationships among Turin's elite, where brief affairs contrast with lasting obligations.

Why they belong together: These films are grouped by their shared focus on the emotional cost of investigation.
