What Happens in I Can’t Sleep: Full Plot Summary

The whole story of I Can’t Sleep (1994) 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.

Daiga, a Lithuanian woman with little money, arrives in Paris with dreams of becoming an actor, but soon finds herself taking a job as a maid in a hotel owned by a friend of her great-aunt. The arrival is quiet but loaded with hesitation, as Daiga steps into a city that feels both familiar and intimidating, where every corridor could hide a new challenge. Daiga

In a parallel thread, Theo is navigating a turbulent home life. He wants to leave Paris for Martinique with their young son, yet his wife resists the move, preferring to stay in the city they know. The tension at home is palpable, and Theo’s visits from his brother—who brings a mix of concern and distance—do little to ease the strain. The city outside buzzes with a darker energy, a string of violent murders targeting elderly women living alone casting a long, unsettled shadow over everyone who moves through its streets.

The killings are carried out by Camille, whose presence in the hotel where Daiga works becomes a troubling link between these two lives. Camille is a figure who moves through the story with a quiet menace, and his lover shares the same dangerous secrecy. The hotel itself becomes a liminal space where private lives collide with public danger, and the fear of who might be watching grows with every new nightfall.

Daiga’s curiosity and the unsettling proximity of Camille pull the two narratives closer. She begins to shadow him, driven by a nagging suspicion that something terrible is unfolding just out of sight. When a police sketch of Camille surfaces, she pieces together enough to confirm that the man is indeed the killer roaming the city’s shadowed avenues and hotel rooms. In a decisive moment, she breaks into his room, discovers a bag of cash, and makes the bold choice to seize what could fund a way out; she then leaves swiftly, aiming to return to Lithuania with a marked sense of resolve and relief.

As the police close in, Camille is spotted after one of the victims manages to provide a description that matches the sketch. The investigation tightens its grip around the hotel and its surrounding streets, while Theo is brought to the police station for questioning. He insists, with a calm, stubborn clarity, that he had nothing to do with the murders and that he had remained oblivious to his brother’s actions throughout the period in question. The tension between truth and suspicion threads through every scene, leaving characters at a crossroads where past loyalties, new desires, and the weight of fear all vie for how they will move forward in a city that never fully reveals its secrets.

Daiga becomes suspicious of Camille after noticing his strange behavior and the fact that he lives at the hotel where the murders are occurring. Her curiosity deepens when she sees a police sketch that matches his face, confirming her growing conviction that he is connected to the killings.

Q2

How does Daiga realize Camille is the killer?

Daiga connects Camille to the murders by recognizing his face from a police sketch that circulates during the investigation. She pieces together his strange behavior, his presence at the hotel, and the timing of the killings to confirm her suspicion. This realization transforms her from a curious observer into someone actively seeking proof.

Foreshadowing: The police sketch appears after the investigation intensifies, providing Daiga with the confirmation she unconsciously already knew.

Q3

Why does Daiga steal the money from Camille's room?

Daiga steals the money because she sees it as her only opportunity to escape her precarious situation in Paris. With little money, no stable acting career, and facing danger from Camille, she views the cash as a way to return to Lithuania and start over. Her decision reflects desperation rather than greed, she prioritizes survival and escape over justice.

Foreshadowing: Earlier scenes establish Daiga's financial struggles and her dream to return home, making the theft a logical extension of her vulnerability.

Q4

How are Theo and Camille related?

Theo and Camille are brothers, with Camille being Theo's younger brother who occasionally visits Theo at his home. This family connection becomes crucial when the police investigate the murders, as Theo's relationship to the killer places him under suspicion despite his claims of ignorance.

Foreshadowing: Theo's brother is mentioned early in the film, but his identity as Camille the killer is revealed later through the investigation.

  • theo
  • camille
  • brothers
  • family relationship
Q5

Why does Theo get questioned by the police?

Theo is questioned because he is Camille's brother, and the police suspect he may have known about or been involved in the murders. During questioning, Theo insists he had no knowledge of Camille's crimes and claims complete ignorance about his brother's activities, though the investigators remain skeptical given the family connection.

Foreshadowing: Theo's earlier visits from his brother establish their relationship before the murders become public knowledge.

  • theo
  • police questioning
  • brother camille
  • suspicion
Q6

Why does Daiga return to Lithuania?

Daiga returns to Lithuania because she fears for her safety after discovering Camille is the killer and stealing his money. Paris has become dangerous and unwelcoming, and the stolen cash gives her the means to leave. She chooses escape over confronting the police or staying in a city where she feels threatened.

Foreshadowing: Daiga's initial arrival in Paris showed hesitation and difficulty, establishing that she always viewed Lithuania as her true home.

His crimes represent hidden violence lurking within the city, with the hotel serving as his hunting ground. The murders create an atmosphere of fear that permeates the entire narrative.

Foreshadowing: The murders are introduced early as a city-wide threat, establishing the danger that eventually connects to the hotel where Camille lives.

Q8

Does Theo know about Camille's crimes?

Theo claims he had no knowledge of Camille's murders and insists he was unaware of his brother's criminal activities. However, the film leaves this question ambiguous. The police doubt his claims due to their sibling relationship, and Theo's assertion of innocence comes across as either genuine ignorance or careful denial.

Foreshadowing: Theo's visits from his brother appear casual but take on new meaning once Camille's crimes are revealed.

  • theo
  • camille
  • knowledge
  • innocence
  • denial
Q9

Q10

Why is the hotel where Daiga works important?

The hotel serves as the central location where multiple storylines converge. It is both Camille's residence and the site where the murders are connected, making it a space of hidden danger. For Daiga, working there places her in immediate proximity to the killer, creating personal stakes in the investigation that affects her directly.

Foreshadowing: The hotel is introduced as Daiga's workplace, but its darker significance emerges as the murder investigation progresses.

Foreshadowing: The victim's survival is unexpected and provides the crucial breakthrough in the otherwise slow investigation.

Foreshadowing: The marital dispute is introduced early, establishing Theo's personal struggles before the murder plotline fully emerges.

Q13

Is Daiga involved with Camille romantically?

The summary does not indicate a romantic relationship between Daiga and Camille. Instead, Daiga's fixation on Camille stems from suspicion and fear rather than attraction. Her tracking of him is driven by the need to understand the danger around her, not by romantic interest.

Foreshadowing: Daiga's pursuit of Camille is portrayed as investigative rather than intimate, though the description mentions fascination with a mysterious figure.
