Luther: The Fallen Sun is a dark, intense continuation of the beloved BBC crime series Luther, bringing Idris Elba’s iconic detective to the big screen. The film is unapologetically grim, morally heavy, and designed as both a reward for longtime fans and a gateway for new viewers.
Detailed Summary
A Serial Killer Who Hunts Through Fear
The film opens with London gripped by terror. A sadistic serial killer, later revealed as David Robey, uses people’s darkest secrets to psychologically torture and manipulate them. He doesn’t just kill; he destroys his victims emotionally first, making him one of the most disturbing antagonists in the Luther universe.
John Luther is already under scrutiny by internal affairs for past rule-breaking. When he fails to stop Robey in time, the consequences are immediate and brutal.
Luther in Prison: A Caged Predator
Luther is arrested and imprisoned, stripped of his badge, authority, and freedom. Even behind bars, his mind never stops working. He knows Robey is escalating and that the police will never catch him using conventional methods.
This section reinforces one of the franchise’s core themes: Luther is most dangerous when cornered, to both criminals and the system meant to contain him.
Escape and Obsession
Driven by guilt and responsibility, Luther orchestrates a violent prison escape. This isn’t portrayed as heroic; it’s desperate, chaotic, and morally questionable. From this moment on, Luther is officially a fugitive, hunted by both the killer and the authorities.
Meanwhile, Robey escalates his crimes, using advanced surveillance, hacking, and psychological profiling to play god with his victims’ lives.
The Investigation Goes International
The chase takes Luther across borders, eventually leading to Iceland, where Robey has retreated to a remote, fortress-like hideout. The bleak, frozen landscape mirrors the emotional emptiness of the villain and the mental state Luther is slipping into.
This section of the film leans heavily into thriller-horror territory, with long silences, isolation, and dread replacing fast-paced police procedural elements.
Movie Ending
The final act takes place at Robey’s heavily secured compound. By this point, it is revealed that Robey’s motivation stems from his childhood trauma and obsession with control. He believes exposing people’s secrets and punishing them makes him morally superior.
Luther confronts Robey directly, engaging in a brutal psychological and physical showdown. Robey attempts to prove that Luther is no different from him, arguing that Luther also believes the ends justify the means.
This is the central question of the film:
Is Luther a necessary evil, or just another man who breaks rules because he believes he’s right?
Luther ultimately stops Robey, saving potential victims and ending the killer’s reign. However, there is no triumphant victory. Luther surrenders himself willingly, accepting responsibility for his actions.
In the final moments, Luther is taken into custody once again. The ending is intentionally ambiguous but heavily suggestive: powerful figures intervene behind the scenes, hinting that Luther may be recruited for covert operations rather than left to rot in prison.
The film closes on Luther being transported, his fate uncertain, but his story clearly not over.
Are There Post-Credits Scenes?
No, there are no post-credits or mid-credits scenes. However, the ending itself functions as a soft setup for future installments, strongly implying that John Luther’s story will continue in some form.
Type of Movie
Luther: The Fallen Sun is a dark crime thriller with strong elements of psychological horror and neo-noir, focusing more on obsession, guilt, and moral ambiguity than traditional detective work.
Cast
- Idris Elba – John Luther

Andy Serkis delivers a particularly chilling performance, proving once again that he doesn’t need motion capture to be terrifying.
Film Music and Composer
The score was composed by Lorne Balfe, whose music emphasizes tension and unease rather than melody. Heavy use of low-frequency sounds, minimalistic themes, and sudden crescendos amplify the film’s oppressive atmosphere.
Filming Locations and Their Importance
- London, England – Grounds the story in the familiar Luther world of urban decay and institutional pressure
- Iceland – Represents isolation, emotional coldness, and the god-like control Robey believes he possesses
The stark contrast between crowded London and empty Iceland reinforces the film’s thematic shift from public chaos to private horror.
