Luther: The Fallen Sun

Robey specifically targets Luther because he discovered evidence of Luther's corrupt past as a police officer. Rather than simply killing Luther, Robey wants to destroy him psychologically by exposing his hypocrisy, Luther who considers himself above the law is now powerless while Robey controls everything.

Earlier in the film, Robey is shown blackmailing and manipulating people, establishing his preference for psychological warfare over direct violence.

Robey, portrayed as a wealthy and resourceful individual, conducts extensive surveillance and investigation into Luther's history. Through this digging, he uncovers records of Luther's illicit actions during his time as a police officer, specifically the corrupt methods Luther used to catch criminals.

The film establishes Robey as a wealthy trader with significant resources and intelligence networks.

Robey lures the families, including Corinne, Callum's mother, to a desolate house where he sets their children's remains ablaze. This act serves multiple purposes: it maximizes psychological torture for the grieving parents, demonstrates Robey's complete lack of humanity, and taunts Luther by involving the family of someone he failed to save.

A malfunctioning mobile phone battery ignites the fire, showing how Robey's elaborate plans still rely on random chance.

Robey smuggles a recording of Callum's murder into Luther's cell through a radio frequency. The recording is physically brought into the prison and hidden, allowing Robey to psychologically torment Luther from afar. This demonstrates Robey's extensive reach and ability to manipulate events outside his immediate presence.

The timeline establishes Robey as someone who orchestrates complex schemes involving multiple people.

Raine dismisses Luther's warnings because she views him as a "dirty cop" who was rightfully dismissed from the force. She prioritizes protecting her own investigation and sees Luther as a liability who could compromise her case. Additionally, she doesn't yet understand the full scope of Robey's threat.

Raine's initial coldness toward Luther establishes the tension that must be overcome for their eventual partnership.

Robey kidnaps Anya to force Raine into a position of vulnerability and helplessness, mirroring what he did to Corinne and other families. By targeting Raine's daughter, Robey turns the hunter into the hunted and creates the personal stakes needed to draw both Raine and Luther into his twisted game.

Robey previously targeted the families of his victims, establishing a pattern of using loved ones as psychological leverage.

The Red Bunker is a sinister online "red room" where captives are tortured for live entertainment watched by paid viewers across Europe. Hosted in Robey's mansion in rural Norway, these sadistic livestream events represent the darkest extension of Robey's psychopathy, turning murder into spectacle and profit.

Raine's team uncovers the Red Room investigation before they realize its connection to Robey.

Luther discovers the radio station broadcasting Robey's messages and questions the station owner, who provides crucial information about a dangerous encounter that went wrong. This leads Luther to connect the dots and track Robey to his rural Norwegian mansion where the Red Bunker events take place.

The timeline shows Luther investigating the radio station as a key breakthrough in locating Robey.

Georgette is Robey's disfigured ex-wife. Luther discovers this connection and realizes Robey has a pattern of ties to individuals he has tormented, suggesting Robey's violence extends to those closest to him and that his abuse was not limited to his serial killing victims.

The connection is revealed as Luther investigates Robey's personal history and relationships.

Robey dies during a final confrontation with Luther and Raine at a frozen lake near his Norwegian mansion. After a deadly struggle, Robey falls into the icy water and sinks to his death, ending the threat he posed but not without leaving lasting scars on Luther.

The frozen lake setting is established as they approach Robey's mansion, creating tension for the climactic showdown.

Luther escapes because Robey's threats are escalating, taunting him with recordings, targeting families, and planning something sinister. With Raine refusing to help and the police dismissing him, Luther concludes the only way to stop Robey is to take matters into his own hands, even if it means breaking the law he once swore to uphold.

The timeline shows Luther's growing desperation as Robey's influence expands while he's confined.

After being rescued from the frozen lake, Luther is approached by Cranfield, a mysterious MI5 figure who offers him a way out of returning to prison. The offer suggests Luther could work for British intelligence, potentially giving him a new purpose and a legal alternative to his previous methods of pursuing justice outside the system.

The film ends on this ambiguous note, leaving Luther's future uncertain but hinting at a new chapter.
