In 1984, civilisation has been ravaged by world war, civil conflict, and revolution. Airstrip One (formerly known as Great Britain) is a province of Oceania, one of the three totalitarian super-states that rule the world. It is ruled by "The Party" under the ideology of "Ingsoc" (a Newspeak shortening of "English Socialism") and the mysterious leader Big Brother, who has an intense cult of personality. The Party brutally purges out anyone who does not fully conform to their regime, using the Thought Police and constant surveillance through telescreens (two-way televisions), cameras, and hidden microphones. Those who fall out of favour with the Party become "unpersons", disappearing with all evidence of their existence destroyed.
In London, Winston Smith is a member of the Outer Party, working at the Ministry of Truth, where he rewrites historical records to conform to the state's ever-changing version of history. Winston revises past editions of The Times, while the original documents are destroyed after being dropped into ducts known as memory holes, which lead to an immense furnace. He secretly opposes the Party's rule and dreams of rebellion, despite knowing that he is already a "thought-criminal" and is likely to be caught one day.
