Nineteen Eighty-Four follows Winston Smith, a minor official in the totalitarian state of Oceania, where the ruling Party controls public information, monitors citizens and demands loyalty to its leader, Big Brother. Winston works at the Ministry of Truth, altering historical records so that the past always conforms to the Party’s current claims.

Privately sceptical of the regime, Winston begins an illicit relationship with Julia and seeks evidence that resistance to the Party is possible. Their rebellion brings them into contact with O’Brien, whom Winston initially believes to be an ally. Instead, Winston is arrested, interrogated and subjected to psychological and physical coercion designed to eliminate independent thought.

The novel examines surveillance, propaganda, censorship, manipulated language and the political control of memory. Through concepts such as Newspeak, doublethink and thoughtcrime, Orwell explores how authoritarian power can attempt to reshape both public reality and private belief.
