Airstrip One is part of the vast political entity Oceania, which is eternally at war with one of two other vast entities, Eurasia and Eastasia. At any moment, depending upon current alignments, all existing records show either that Oceania has always been at war with Eurasia and allied with Eastasia, or that it has always been at war with Eastasia and allied with Eurasia. Winston Smith knows this, because his work at the Ministry of Truth involves the constant "correction" of such records. "'Who controls the past,' ran the Party slogan, 'controls the future: who controls the present controls the past.'"
In a grim city and a terrifying country, where Big Brother is always Watching You and the Thought Police can practically read your mind, Winston is a man in grave danger for the simple reason that his memory still functions. He knows the Party's official image of the world is a fluid fiction. He knows the Party controls the people by feeding them lies and narrowing their imaginations through a process of bewilderment and brutalization that alienates each individual from his fellows and deprives him of every liberating human pursuit from reasoned inquiry to sexual passion. Drawn into a forbidden love affair, Winston finds the courage to join a secret revolutionary organization called The Brotherhood, dedicated to the destruction of the Party. Together with his beloved Julia, he hazards his life in a deadly match against the powers that be.
