Davey Graham makes an entrance at an upscale party, his intention clear as he tries to make a drug deal with a woman named Stella. However, just as he is about to leave, her date observes him and promptly makes a call on his mobile phone, setting off a chain of disturbing events. Outside the venue, three men are waiting in a black Range Rover, one of whom is a car dealer named Boad. As Davey walks through the streets of London, unaware of the impending danger, the men begin to tail him. The chase culminates in a brutal assault right as he's about to return home. Two of the men confront him directly, pinning him down while another lurks menacingly in an alley. They silence his desperate cries for help, dragging him into a nondescript garage where a horrific act of violence unfolds—Boad rapes him.
As dawn breaks, a disoriented Davey stumbles out of the garage, his world irrevocably shattered, and returns home to seek solace in a bath, fully clothed, as if trying to wash away the trauma. Hours later, his friend Mickser arrives, only to find Davey lifeless in the bathtub, his throat slashed in a final act of despair. Devastated, Mickser seeks out Helen, hoping she can connect him with Davey's brother, Will. Helen informs him that she has lost contact with Will—a brother who deceptively vanished from their lives three years ago.
Will has retreated into the countryside, embracing a solitary life as a forester. With unkempt hair and a rugged appearance, his life becomes even more complicated when he loses his job due to bureaucratic issues stemming from a lack of documentation. On the verge of leaving England for good, he has an unsettling vision of Davey at the ferry terminal, but soon realizes it’s merely a hallucination. Concerned, he tries to reach out to Davey's apartment but gets no response, prompting him to return to London, where he is greeted with the heartbreaking news of his brother's death. This shocking revelation not only brings Will face-to-face with his brother's brutal fate but also stirs unease within crime boss Frank Turner, who sends a cautionary message, advising Will to leave the city after paying his respects.
Despite the threat, Will's old gang urges him to reclaim his previous life, insisting that Turner is vulnerable. Yet, Will firmly rejects the notion of returning to the criminal underworld. Instead, he visits Helen to express his regret for abandoning her, reflecting on the tragic—yet wasted—lives of both himself and Davey. Driven by grief and a desire for answers, Will pushes for a second post-mortem to investigate the circumstances surrounding Davey's tragic end. The findings reveal the brutal truth: Davey was raped before his death, a fact compounded by the brutal and humiliating realization that he involuntarily ejaculated during the assault. This revelation is further explained by the coroner, who embarks on a discussion about the psychological ramifications of such violence, ultimately leading Will to seek the counsel of a psychologist to help him understand the complex mental toll of rape and its survivors.
As what seems to be a string of devastating events unfold, Mickser tracks down the man who had watched Davey leave the party and, through their detective work, they hone in on Boad. During a cunningly orchestrated dinner at Boad's residence, Will begins to plot his revenge. Tensions in the streets rise; Will's gang pulls a prank at Turner’s domain that embroils them deeper in the criminal fray, prompting Turner to dispatch an Irish hitman to enforce his will upon Will. In a moment of personal reckoning, Will discovers a vintage Jaguar hidden away in a garage, along with a suitcase replete with cash, attire, and a gun—all symbols of a past life he cannot escape.
Will undergoes a dramatic transformation, shedding his unkempt persona for a polished, suit-clad figure ready to confront his brother's tormentor. He washes the Jaguar and makes the fateful decision to call Helen, instructing her to pack a bag in anticipation of a new chapter, yet unbeknownst to him, danger lurks nearby in the form of Turner's hired hitman. Arriving at Boad's home, Will inadvertently sets off an alarm, bringing Boad into the open. A tense confrontation arises where Will confronts Boad, who coldly reveals his fascination with Davey's seemingly charmed life—believing that stripping him of his facade would somehow reveal a true, worthless self beneath.
In a moment that defines both revenge and moral complexity, Will decides against the instant gratification of killing Boad—believing it would be too simple and easy. He then walks away but is consumed by rage, only to return to deliver a swift and unforgiving end to Boad. Meanwhile, Helen awaits with her arms crossed, anticipating Will's arrival amidst the tension brewing from Turner's approaching threats. The film culminates in an ambiguous yet poignant climax as Will reflects on a man hitting golf balls into the ocean—a motif echoed by the film's opening sequence. In the final moments, he ponders the essence of memory and loss, suggesting that when someone is gone, what endures are merely the remnants of their existence, as he drives away, leaving behind the haunting echoes of his brother’s life and death.
