Slimane exploits Pépé's love for Gaby by setting a trap at the airport rather than the hotel. After learning that Pépé plans to flee to Paris with Gaby, Slimane has Carlo (who is secretly working for him) misdirect the situation. Gaby is told Pépé has been killed, forcing her to leave on an earlier flight. When Pépé arrives at the airport, Slimane waits with police. A stranger offering Pépé a cigarette light alerts authorities to his presence, allowing them to capture him.

Foreshadowing: Slimane realizes early that Pépé's love for Gaby is his weakness and uses this emotional vulnerability as bait for the trap.

Gaby never arrives at the hotel because Slimane's plan involves deceiving her. Carlo reveals to Pépé that Gaby was duped into believing Pépé had been killed. This false information causes Gaby to believe her lover is dead, and she goes to the airport to leave Algiers instead of waiting for Pépé at the meeting point.

Foreshadowing: Carlo's dual role as Pépé's sidekick and Slimane's informant is hinted at when he assists with the escape but then provides information to the police.

Pépé is shot while recklessly running toward Gaby at the airport. After being discovered by the police through the cigarette lighter incident, he makes a desperate dash toward the airplane where Gaby sits unaware at the window.

Foreshadowing: The fatalistic tone is established early, the Casbah is portrayed as a prison from which Pépé cannot escape, no matter how far he runs.

Carlo, Pépé's trusted sidekick, is secretly working with Detective Slimane throughout the film. His betrayal is not fully explained in the summary, but his role as a double agent allows Slimane to track Pépé's movements and set up the final ambush at the airport. Carlo's deception enables the police to know exactly when and where Pépé will attempt to escape.

Foreshadowing: Carlo assists Pépé with the escape, but his access to the plans and movements makes him the logical source of information leaking to Slimane.

Pépé's fate is inevitable because the Casbah has become both his sanctuary and his prison. While he rules the criminal underworld within its walls, he cannot truly leave it, the police understand this and wait for him to step outside. His love for Gaby gives him the motivation to take the fatal risk, but Slimane has already anticipated this weakness. The film establishes that a man like Pépé, deeply tied to the Casbah's underworld, cannot simply walk away and start fresh.

Foreshadowing: The opening establishes Pépé's exile and the police's persistent efforts to lure him out, setting up the theme that escape is impossible.

The cigarette lighter moment is the key instant that betrays Pépé's presence at the airport. As he attempts to board the plane, a stranger offers him a light for his cigarette. This simple interaction draws attention to Pépé, allowing police to identify and surround him. The lightness of the gesture contrasts with the gravity of the moment, a small act of kindness ultimately leads to his discovery and capture.

Foreshadowing: Slimane's plan relies on waiting for Pépé to make a mistake in public, and the airport provides minimal cover compared to the maze-like Casbah.

Inez screams because despite her betrayal, she still has feelings for Pépé. When she cooperated with the police, she likely expected Pépé to be captured, not killed. Her scream as she watches him recklessly run toward Gaby reveals her emotional conflict, she wanted to stop him from leaving, not witness his death. Her presence at the airport and her reaction show the tragic consequences of her jealousy-driven decision.

Foreshadowing: Inez's earlier jealousy and her attempt to keep Pépé anchored to her foreshadow the destructive nature of her emotions.

Pépé chooses Gaby because she represents escape from his criminal life into a legitimate future in Paris. While Inez is his loyal girlfriend within the Casbah, she is tied to his life as a thief. Gaby, as a French tourist, symbolizes a way out, an opportunity to leave his past behind and start fresh. Pépé tells Inez directly that he will never forget her but is leaving, indicating that his desire for a new life with Gaby outweighs his existing relationship.

Foreshadowing: Pépé's flirting with Gaby on the yacht triggers Inez's jealousy and establishes the romantic conflict that drives the story's tragic ending.

Slimane deduces Pépé's escape plan by understanding his love for Gaby. When Inez realizes Pépé has fallen in love with Gaby and intends to follow her to Europe, she informs Slimane of this development. Recognizing this emotional vulnerability, Slimane shifts his strategy from simply luring Pépé out of the Casbah to setting a trap at the point of escape. By monitoring Gaby's movements and knowing she plans to leave, Slimane positions his police at the airport to intercept Pépé.

Foreshadowing: Slimane's dialogue indicates he has studied Pépé's psychology, noting that love for Gaby would be the one thing to make him leave the Casbah.
