Calibre: The Netflix Thriller That Turns a Hunting Trip Into a Nightmare
A weekend hunting trip in the Scottish Highlands takes a devastating turn in Calibre, a psychological thriller that has left viewers praising its relentless tension and deeply uncomfortable moral questions.
Released in 2018 after premiering at the Edinburgh International Film Festival, the film stars Jack Lowden and Martin McCann as two lifelong friends whose getaway quickly descends into a nightmare neither of them could have anticipated.
What begins as a remote escape soon becomes a desperate attempt to get home without exposing what happened. Every choice they make brings new consequences, putting their friendship, their sense of right and wrong, and ultimately their chances of escape under increasing pressure.
The film has since earned a perfect 100% critics’ score on Rotten Tomatoes, while viewers continue to recommend it for its slow-burning suspense, unexpected turns and unsettling realism.

When a hunting trip goes wrong
Lowden and McCann play two friends who travel deep into the Highlands for a hunting weekend.
Their plans change after a devastating incident, forcing them to confront a situation that becomes increasingly difficult to control.
Rather than focusing on a conventional villain or elaborate action, Calibre builds its suspense around the consequences of what happens next. The two men must figure out how to leave the nearby village without arousing suspicion, while fear and guilt begin to put their relationship under immense strain.
The more they try to protect themselves, the more complicated their situation becomes.
One decision leads to another, creating a chain of consequences that leaves them with fewer and fewer options.

Scotland’s Highlands add to the tension
The film’s remote Scottish setting is more than just a backdrop.
At first, the Highlands provide exactly what the characters are looking for: dramatic scenery, solitude and an escape from everyday life. But once their situation begins to unravel, that same isolation becomes increasingly unsettling.
The beauty of the landscape stands in stark contrast to the events unfolding within it, creating an atmosphere that grows darker as the story progresses.
Martin McCann has previously spoken about the film showcasing the beauty and majesty of Scotland, while the cast also features Scottish actors Tony Curran and Fort William-born Kate Bracken.
Still, the heart of the film remains the relationship between Lowden and McCann’s characters as they struggle with fear, loyalty and the consequences of their actions.

Viewers continue to praise the slow-burn suspense
Much of Calibre‘s appeal comes from the way it gradually increases the pressure rather than relying on constant action.
One viewer described the film as “a master class in storytelling,” praising the performances and dialogue alongside its ability to build suspense from scene to scene. They also highlighted its unexpected twists and said the ending stayed with them after the credits.
Another viewer called it one of the best films of its genre they had seen in years, particularly praising Matt Palmer’s approach to slow-building tension.
Other viewers have responded to the film’s central moral dilemma, finding themselves wondering how they might react if placed in a similar situation.
One described Calibre as “very realistic yet very tragic” and argued that the film deserved more recognition.
The most unsettling part is what comes next
The horror of Calibre comes from the fact that its central crisis feels grounded in human decisions.
The characters aren’t simply trying to uncover a mystery or escape a clearly defined enemy. Instead, they are dealing with the aftermath of a tragedy while attempting to make difficult choices under extreme pressure.
As the situation deteriorates, the film raises uncomfortable questions about guilt, responsibility and how far someone might go to protect themselves or someone they care about.
One viewer praised the way the story makes audiences “question their moral code,” particularly as one mistake begins to lead to another. They also singled out the film’s visuals and described the tension as “palpable.”
Another praised the plot, performances and final twist.

A tense film for one-night viewing
At just one film, Calibre doesn’t require the commitment of a long-running series. Its story is contained within a single, increasingly tense journey, making it an easy choice for viewers looking for something gripping to watch in one evening.
The film’s 100% Rotten Tomatoes critics’ score is certainly striking, but its continued recommendations from viewers point to what has kept it memorable years after its release.
With its isolated Scottish setting, plausible premise and steadily escalating suspense, Calibre turns one terrible moment into a chain of decisions that becomes increasingly difficult to escape.
Calibre is currently available to stream on Netflix.
