In a dystopian future, Britain falls under the oppressive rule of the Norsefire political party, a totalitarian regime led by High Chancellor Adam Sutler. This regime manipulates the populace through relentless propaganda and eradicates anyone deemed undesirable, such as immigrants, homosexuals, and individuals with differing beliefs.
The story follows Evey Hammond, whose childhood was shattered when her activist parents, fighting against the regime, were imprisoned and died when she was just twelve. Evey's life takes a drastic turn when, one fateful evening, she is rescued from an attack by the secret police, known as the Fingermen, by a masked vigilante called V. This cryptic figure not only saves her but also introduces her to the world of rebellion by detonating the Old Bailey, a symbol of the regime's power.
On November 5, V seizes control of the state-run television to deliver a powerful message to the nation, taking credit for the bombing and urging the citizens to rise against Norsefire. In an attempt to protect her from the impending danger, V takes Evey under his wing, but their journey becomes tumultuous as V sets out to avenge the wrongs inflicted by the regime, targeting key figures such as Lewis Prothero, Dr. Delia Surridge, and Anthony Lilliman, a corrupt bishop.
Evey, who initially assists V in his quest, finds herself torn between her allegiance to him and her desire for safety. After a betrayal, she seeks refuge with her former boss, Gordon Dietrich, a talk show host who, inspired by Evey and V, challenges the regime publicly, ultimately leading to his own execution. In her darkest moments, Evey discovers a note from Valerie Page, a fellow prisoner whose optimism in the face of death strengthens Evey's resolve.
Enduring psychological torment, Evey learns to confront her fears and ultimately vows to return to V before his planned uprising on November 5. As the date approaches, V’s influence spreads; he distributes countless Guy Fawkes masks, igniting a wave of defiance among the populace, culminating in chaos when the secret police kill an innocent masked girl.
In a poignant moment, V and Evey share a dance before descending into the secret underground network he meticulously restored over the years. Knowing he may not survive the looming conflict, V entrusts Evey with the fate of an explosive-laden train intended for destruction on that significant night. Despite her desperate pleas for him to abandon his mission, V remains resolute.
As the climactic showdown occurs, V slays Peter Creedy and his henchmen after a fierce confrontation, declaring that the ideas he embodies will outlive him. He confesses his love for Evey before succumbing in her arms. With the demise of Sutler and Creedy, London’s armed forces surrender as a multitude of masked citizens converge upon Parliament, witnessing its dramatic obliteration.
When Chief Inspector Eric Finch inquires about V's true identity, Evey replies with profound resolve, "He was all of us." This encapsulates the spirit of a united resistance against tyranny, leaving a legacy of hope for the oppressed.
