A troubled teenager disappears from the streets and awakens inside a seemingly ordinary suburban house, restrained by a man who insists he is trying to save him. Stephen Graham delivers a deeply unsettling performance in The Good Boy, a psychological thriller that transforms the familiar idea of rehabilitation into a terrifying struggle for control. What begins as an apparent attempt to rescue a young man from a destructive lifestyle gradually exposes a far more disturbing question: what happens when someone becomes convinced that cruelty is an act of kindness?

At the centre of this nightmare is Tommy, a 19-year-old played by Anson Boon, whose existence revolves around reckless nights, substance abuse and increasingly violent behaviour. His future appears to be heading toward disaster, but nothing prepares him for the punishment awaiting him after a mysterious abduction.

When Tommy regains consciousness, he finds himself trapped in an unfamiliar basement with a chain fastened around his neck. The house belongs to Chris, portrayed by Graham, a seemingly respectable family man whose calm demeanour conceals an extraordinary willingness to control another human being.

Chris does not present himself as a conventional villain. Instead, he believes he is offering Tommy something the young man desperately needs: discipline, stability and a chance to become a better person.

Yet the disturbing reality is that Tommy has never agreed to any of it.

A FAMILY THAT BELIEVES CAPTIVITY CAN BECOME SALVATION

The situation becomes even more unsettling when Chris’s wife Kathryn, played by Andrea Riseborough, enters the picture. Rather than treating Tommy’s imprisonment as an emergency, the household operates around the belief that his captivity serves a greater purpose.

Their young son Jonathan, played by Kit Rakusen, is also part of this strange domestic environment, creating an unnerving contrast between ordinary family life and the suffering concealed beneath the same roof.

Tommy is confronted with a terrifying choice: submit to the family’s demands or attempt to escape from people who believe their actions are justified.

The psychological tension emerges not simply from the chains or locked rooms, but from the frightening certainty with which Chris approaches his mission.

Graham’s character occupies a morally disturbing space between self-appointed rescuer and ruthless captor. His apparent concern for Tommy makes his methods even more difficult to comprehend.

And as the power struggle intensifies, the difference between helping someone and destroying their independence becomes increasingly impossible to ignore.

STEPHEN GRAHAM BRINGS A CHILLING INTENSITY TO THE ROLE

Known for his powerful performances in Adolescence, Boiling Point and other acclaimed dramas, Graham has built a reputation for portraying complicated characters whose emotions can shift dramatically beneath the surface.

In The Good Boy, that intensity is channelled into a character whose frightening behaviour is wrapped in the language of responsibility and moral improvement.

Opposite him, Boon’s Tommy is no innocent figure. His history of aggression and self-destructive behaviour complicates the audience’s sympathies, forcing viewers to confront an uncomfortable dilemma.

Can someone who has caused harm still be considered a victim when subjected to abuse himself?

And can a person genuinely claim to be helping another while stripping away their freedom?

These questions give the film a disturbing psychological dimension beyond its central captivity storyline.

THE DARK VISION BEHIND THE FILM

Directed by Oscar-nominated Polish filmmaker Jan Komasa, The Good Boy explores the dangerous consequences of moral certainty.

The screenplay was initially conceived in Polish with Warsaw as its setting before being reworked into an English-language story located in Yorkshire.

Komasa was particularly attracted to the screenplay’s dark humour and its exploration of ethically ambiguous behaviour, themes that allow the story to move beyond a conventional abduction thriller.

Rather than offering an obvious division between good and evil, the film challenges viewers to examine how easily noble intentions can become excuses for manipulation.

Riseborough’s mysterious Kathryn adds another layer of unease, while the family’s isolated domestic setting creates an atmosphere in which ordinary routines begin to feel threatening.

The film is listed for viewing through Prime Video and Apple TV, with access depending on location.

But the most disturbing element of The Good Boy is not simply whether Tommy can escape his confinement. It is the possibility that Chris genuinely believes every terrifying decision he makes is justified — and that the real purpose of his rehabilitation experiment may be something far more sinister than Tommy ever imagined…
