Jack O’Connell proves effective within this harsh and realistic drama, even if neither he nor Sean Harris could be called actors with a wide range. He portrays a soldier, "Hook," who finds himself isolated from his unit after an incident in Belfast where a colleague is fatally shot; he then becomes the target – without a weapon – as he navigates a dangerous city environment. Suffering from injuries and confusion, he’s acutely aware that members of the Provisional IRA are hunting him with lethal intent. What follows is a tightly controlled and economical portrayal of how the conflict affected people of different beliefs during that period. Even those strongly committed to either unionism or republicanism might find themselves at odds regarding violence's place in their cause, and as we observe "Hook’s" journey, we meet numerous individuals where compassion and basic humanity are paramount. The film’s visuals contribute significantly to the atmosphere – primarily shot handheld, under nighttime streetlights – creating a palpable sense of danger. A question arises: will he survive? Politically, it suggests that things in this region were far from simple; people with competing agendas consistently create obstacles for him, which are as frustrating as they are surprising. It’s naturally speculative; the full truth about this conflict may forever remain elusive, but O'Connell, Sam Reid, and Harris contribute to a disturbing look at events occurring not long ago in one of the world’s most established democracies.
