Winston Smith is a clerk in one of Party Ministries; in Ministry of Truth. He's job is to change history or simplified; to change written historical documents so they appear just like Party want them to look so they can show that everything what
Party ever did was good and what Party is doing now is maybe even better.
One day he mets Julia, young girl who also works in Party. After she gave him a ''I love you'' note, they start a relationship. For them, it's an act of standing against Party. Every kind of relationship or sex between Party Members is forbidden. In marriage, sex is only allowed for reproduction; for creating new Party members. They shouldn't feel anything for any other mens; only love for Big Brother and Party. Therefore, they are in constant fear of Thought Police but also, they promise each other they they will go with it all till the end, which will undoubtedly come, because everyone gets caught and everyone confess, according to Julia. Winston doesn't agree, even if he confess; that doesn't change his feelings.
Winston and Julia; lovers and rebels, are trying to become members of anti-Party Brotherhood. Winston wants it because of his believe that there was history; that there was something else except Party. Julia is not sure if Winston is right, but rebelion inside of her also wants to act against Party. Of course, everything was a setup by Thought Police end they end up caught in room above antique store; a place of their usual meeting. During period of torture and brainwashing by O'Brien, Smith surrenders intellectually, but keep his idea: he knows he will
eventually be killed, but secretly he intends to continue hating Big Brother an Party - and loving Julia. It's his only victory against Party, just like he said to Julia - he can confess, but they can't change his inner feelings.
However, Smith's resolve to continue loving Julia is burned away when he finally enters Room 101. Smith has a particular horror of rats. Knowing this, O'Brien threatens to let rats devour Smith's face, and in utter desperation he finally begs his torturers that they do this to Julia instead. Same thing happened to Julia. She had to face with probably her greatest fear - multiple rape by Party Members.
Party again won. They successfully killed any human emotions in Winston and Julia and forced them to betray and deny one each other. They are meeting again but they realize that it doesn't matter any more - they don't like each other any more. Their feelings of love are replaced by greater and purer feelings - love for Party and Big Brother and that was the greatest victory Party could achieve. ''I love Big Brother!'' happily said Winston...
