What Happens in The Colonel: Full Plot Summary

The whole story of The Colonel (2006) 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.

France, 1993. The retired Le colonel Raoul Duplan is shot in his home. As the police are baffled, a young army officer Le lieutenant Galois is brought in to help the investigation. Shortly thereafter she receives a letter containing diary pages from Le lieutenant Guy Rossi, who served in 1955 in the Algerian War under Le colonel Raoul Duplan and disappeared in 1957 under mysterious circumstances. The diary becomes a thread that binds present events to Rossi's memories, sending the narrative back and forth between the present and the hidden history of the Algerian conflict.

As Galois reads Rossi's diary, the film flashes to stark black-and-white sequences that document Rossi's experiences in the war: he witnesses torture and public executions, and he wrestles with a desire for peace while repulsed by the brutal methods used to secure it. He inadvertently reveals information to a friend sympathetic to the rebels, which may have contributed to the murder of a shopkeeper who provided information to the French army. Ordered by Le colonel Raoul Duplan to command a firing squad, Rossi resolves to disobey his superior's orders. He leaves the diary with a friend, intending that Le père Rossi would receive it.

A recent appearance on TV by Duplan prompts the friend to deliver the diary to Rossi's father. When confronted by [Le lieutenant Galois], the elder Rossi reveals that he has been the one sending the diary and that he killed the shopkeeper because Duplan expressed no remorse for his son's murder, justifying himself by accusing Rossi of treachery. The film ends on an ambiguous note as [Le lieutenant Galois], an army officer, lacks the authority to arrest the elder Rossi, and as she drives away from the interview, she seems moved and chooses to have lunch with her commanding officer rather than return to the office.

The Colonel Plot Explained: Your Questions Answered

The questions people ask most about The Colonel (2006): 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 Rossi kill the shopkeeper?

Rossi's father killed the shopkeeper because Duplan showed no remorse for ordering Rossi's death. When Duplan labeled Rossi a traitor, the father saw the shopkeeper - who had been helping the French and was indirectly responsible for Rossi's fate through Rossi's own careless disclosure - as an extension of Duplan's cruelty. The father sought revenge against someone connected to the French military apparatus that destroyed his son.

Foreshadowing: Earlier, Rossi's disclosure to his friend about rebel movements led to the shopkeeper's involvement with the French, creating the chain of events.

  • shopkeeper murder
  • duplan
  • algerian war
  • revenge
Q2

What happened to Rossi after he disobeyed the firing squad order?

After refusing to command the firing squad, Rossi knew his life was in danger. He left his diary with a trusted friend, instructing that it be delivered to his father if anything happened to him. He disappeared in 1957 under mysterious circumstances - Duplan had him labeled a traitor, suggesting he was either killed or forced into hiding.

Foreshadowing: Rossi's refusal to follow orders directly led to his disappearance, as Duplan would not tolerate disloyalty.

  • firing squad
  • duplan
  • traitor
Q3

Who killed Colonel Duplan and why?

Colonel Duplan was shot in 1993. While the exact killer is not explicitly confirmed in the provided text, the investigation centers on the consequences of his actions during the Algerian War. The diary reveals his involvement in war crimes and his role in Rossi's fate, making the shooting likely connected to those exposed truths.

Foreshadowing: The diary pages expose Duplan's brutal methods and his treatment of Rossi, creating motive for someone seeking justice or revenge.

  • duplan killed
  • 1993 shooting
  • investigation
  • murder
Q4

How did Rossi's disclosure lead to the shopkeeper's death?

Rossi accidentally revealed information to a friend who sympathized with the rebels. This friend passed the information along, which eventually reached the rebel side. The shopkeeper, who had been providing information to the French army, was killed as a result. Rossi's carelessness directly caused the death of an innocent civilian who was helping the French.

Foreshadowing: This moment shows the dangerous consequences of Rossi's divided loyalties and his failure to maintain operational security.

  • rossi disclosure
  • shopkeeper death
  • rebel
  • french army
Q5

Why did Rossi's father send the diary to Galois in 1993?

After seeing Colonel Duplan appear on television in 1993, Rossi's friend decided it was time to deliver the diary. The TV appearance of the unremorseful Duplan - still a public figure after decades - prompted the friend to finally send the diary to Rossi's father, who then forwarded it to Galois. The timing was meant to expose Duplan's past crimes while he remained in the public eye.

Foreshadowing: The TV appearance reactivates the past and brings decades-old secrets into the present.

  • diary delivery
  • 1993
  • tv appearance
  • expose duplan
Q6

What did Rossi witness in Algeria that haunted him?

Rossi witnessed torture and public executions conducted as part of the French military's efforts to suppress the Algerian independence movement. He was torn between his desire for peace and his revulsion at the brutal methods used to achieve it. These experiences formed the moral core of his diary and his eventual decision to disobey orders.

Foreshadowing: The black-and-white flashbacks throughout the film emphasize the stark brutality that shaped Rossi's conscience.

  • torture
  • executions
  • algeria
  • warcrimes
  • brutality
Q7

Why can't Galois arrest Rossi's father?

Galois lacks the authority to arrest Rossi's father because she is an army officer, not a civilian police officer. The legal system prevents her from making an arrest outside her jurisdiction. This legal limbo reflects the film's theme that justice cannot be easily attained for historical crimes.

Foreshadowing: This limitation underscores the film's exploration of how war crimes remain unpunished.

  • galois arrest authority
  • legal limit
  • army officer
  • jail
Q8

What does Galois's decision to have lunch mean at the end?

Rather than returning to her office to continue the investigation, Galois chooses to have lunch with her commanding officer. This suggests she is prioritizing personal connection and reflection over professional duty. She appears moved by what she learned about the war's legacy and the moral complexity of the case, indicating a shift in her understanding of duty and justice.

Foreshadowing: This choice contrasts with her earlier professional detachment as the investigator.

  • galois ending
  • lunch
  • commanding officer
  • duty
  • moral conflict
Q9

Why did Rossi refuse to command the firing squad?

Rossi disobeyed Duplan's order to command a firing squad because he could not participate in executing prisoners. The order represented the ultimate moral line he would not cross. This act of disobedience marked his breaking point with the brutal methods of the French military and directly led to his disappearance.

Foreshadowing: This refusal establishes Rossi's moral compass and explains his father's belief that his son was wrongfully killed.

  • rossi disobey
  • firing squad
  • order refused
  • execution
Q10

What were Colonel Duplan's crimes in Algeria?

Duplan ordered and oversaw brutal tactics including torture and public executions during the Algerian War. He maintained that any means necessary were justified to maintain French control. When Rossi refused to participate in a firing squad execution, Duplan had Rossi labeled a traitor. Duplan showed no remorse for these actions, even decades later when he appeared on television.

Foreshadowing: The diary serves as the primary document exposing Duplan's war crimes.

  • duplan war crimes
  • torture
  • executions
  • algerian war
  • colonel
