When the old Major, a highly respected white boar, gathers his fellow farm animals to preach about freedom, rebellion and the evils of man, he incites a revolution that has been brewing for years. The animals drive out their drunken farmer, Mr Jones and create their own society which promises equality for all. Two scheming pigs, Napoleon and Snowball, appoint themselves leaders and what begins as a supposedly equalitarian community descends into an increasingly violent and hierarchical society permeated by lies and corruption.
