In a stark, restrained drama set against the Troubles-era backdrop of Britain, the narrative follows Gerry Conlon as he becomes enmeshed in a case of catastrophic injustice. The film opens with a grievous mix of mistaken identity and fear: Gerry is misidentified by British security forces as an IRA sniper, sparking a relentless pursuit that crescendos into a riot. To avert an IRA reprisal against him, Gerry is sent from Belfast to London by his father, Giuseppe, a move that sets the stage for a case that will unfold with devastating consequences for their family.
One night, a desperate act lands Gerry in deeper trouble: he breaks into a prostitute’s flat and steals £700. The sequence that follows pulls Gerry into a web of marginal lives—his friend Paul Hill, and a homeless Irishman named Charlie Burke—who share a moment of risk in a park where they use drugs. The Guildford bombing of Guildford soon erupts in the background: four off-duty soldiers and a civilian are killed, and many are wounded. This atrocity becomes the catalyst that drives Gerry back to Belfast, where the authorities seize him on terrorism charges.
Gerry is flown to England, where he, Paul Hill, and two others are branded the Guildford Four. From the outset, the interrogation is marked by coercive pressure, and the suspects are subjected to harsh methods that many would later describe as torture. Gerry vehemently asserts his innocence, yet under the threat of violence toward his father, he signs a confession. The consequence ripples through the Conlon family: Giuseppe is arrested as part of the broader Maguire Seven inquiry. Although Gerry’s defense highlights numerous inconsistencies in the police investigation, the courtroom decision follows a familiar pattern of conviction, and the Guildford Four receive life sentences.
Behind the walls of prison, the story takes a sharper turn. A new inmate, Joe McAndrew, reveals a troubling truth: he was the actual bomber, and he had confessed to the police. The authorities apparently withheld this crucial information in an effort to preserve their narrative and “save face.” The relationship between Gerry and Joe becomes complicated; Gerry’s opinion wavers when Joe escalates a riot by setting a prison guard on fire, an act that hardens Gerry’s mistrust even as new truths begin to surface.
Giuseppe’s death in custody from tuberculosis compounds the family tragedy, and Gerry inherits the long, patient campaign for justice that his father began. Giuseppe’s lawyer, Gareth Peirce, intensifies efforts and uncovers vital new evidence about Gerry’s alibi. A note attached to this evidence reads, “Not to be shown to the defence,” underscoring the procedural failure at the heart of the case. A court appeal, driven by a testimony from Charlie Burke, finally exonerates Gerry and the others, exposing the deep flaws in the original investigation.
The film closes with an unflinching epilogue that traces the ongoing lives of the wrongfully accused and documents the aftermath of the inquiry. The police who investigated the Guildford bombing are never prosecuted, and Giuseppe Conlon is laid to rest in Milltown Cemetery in Belfast. The real perpetrators of the Guildford bombing—despite the mounting evidence—have never been charged, leaving a solemn note about accountability and the limits of justice in a system under stress. Through its careful, unflinching narration, the film portrays how a single misjudgment can cascade into years of imprisonment and family hardship, while also honoring those who fight to overturn a devastating error.
