On a gray, drab night in a small town, a young woman is murdered in an unusually brutal and sadistic manner as she makes her way home from the cinema. The shocking crime sows fear and quick whispers of blame, and the townsfolk settle on Hughie [Terence Knapp], a strangely behaved and not particularly bright local youth who has a habit of wandering the streets at odd hours, collecting stray pieces of debris—especially fragments of broken glass, which, unfortunately for him, were among the weapons used in the attack.
Hughie lives in the lodging house run by his aunt, Auntie B [Ruth Dunning], where a small cast of boarders includes a kindly elderly man who Bible-bashes and a smooth-talking ladies’ man. The police question Hughie, but Superintendent Allen [Patrick Barr] sees no solid evidence tying him to the crime and releases him. Yet the atmosphere in the town grows tense: a second girl is killed, and the locals, convinced of Hughie’s guilt, begin to pursue him with a venomous intent. Death threats echo in the pub as a sense of collective panic takes hold, and the front window of the lodging house is smashed by a large rock, amplifying the sense that no one is safe.
Despite the rising hysteria, Allen remains calm and perceptive. He believes the police may be missing something and refuses to condemn Hughie without more proof. As he digs deeper, his attention shifts from the obvious suspect to others linked to Hughie, looking for a pattern or a hidden connection that could explain the murders. While the town clings to fear, Allen quietly investigates, observing the people connected to Hughie and following leads that others overlook.
The investigation intensifies as Allen shadows a probable suspect through the town streets one night. He moves with careful restraint, and when the moment comes, he catches the guilty party almost in the act, narrowly saving another young woman from a murderous strike. In this tense pursuit of truth, the film builds a quiet, methodical confidence in Allen’s instincts and portrays the danger that can lurk beneath a community’s rush to judgment. The drama rests on the contrast between a town driven by fear and a conscientious detective who strives to see beyond appearances to uncover the real danger hidden in plain sight.
