Alternative future. In England, after a terrible epidemic of an unknown virus has thrown the country into chaos, a brutal dictatorship of an overbearing chancellor is established with all its attendant charms: curfews, the power of party members over ordinary people and, of course, hundreds of secret informers. One night, a freedom fighter known as V appears in London and begins a guerrilla war against the regime in an attempt to restore to the people the freedom taken from them. In this war, he brings to his side a young woman whom he has plucked from the clutches of the secret police.
