Read the complete plot summary and ending explained for The Colonel (2006). From turning points to emotional moments, uncover what really happened and why it matters.
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.
Follow the complete movie timeline of The Colonel (2006) with every major event in chronological order. Great for understanding complex plots and story progression.

In the early 1990s, Paris glimmers with a quiet, lingering tension, its elegant streets and historic cafés serving as a backdrop for a mystery that reaches back decades. A once‑renowned officer, now a retired Colonel Raoul Duplan, is found dead under enigmatic circumstances, pulling the city’s present into the shadows of its colonial past. The investigation is handed to a young, diligent officer, Lieutenant Galois, whose sharp mind and sense of duty clash with the murky bureaucracy of the modern French forces. Her arrival awakens a lingering curiosity about the nation’s unresolved history.
As Lieutenant Galois begins to probe the case, she receives a fragmentary diary belonging to Lieutenant Guy Rossi, a soldier who vanished in the turmoil of 1956 Algeria. The notebook, written in stark, almost lyrical prose, becomes a portal to a world of stark black‑and‑white recollections—military patrols, uneasy alliances, and the moral ambiguities that framed a brutal conflict. Through these pages, the film weaves a tense, atmospheric dialogue between the present‑day inquiry and the distant, hidden chapters of a war that still haunts the French conscience.
The tone of the story balances the cool, procedural rhythm of a contemporary police drama with the haunting, almost poetic resonance of a war memoir. Shadows lengthen over both the Parisian streets and the Algerian desert, suggesting that the past is never truly buried. Lieutenant Galois finds herself navigating not only bureaucratic obstacles but also the weight of memory, duty, and the unspoken questions that arise when personal histories intersect with national trauma. The film invites the audience to contemplate how history’s silent echo shapes the lives of those who dare to listen.
