Napoleon is dead in the Animal Farm and is succeeded by his son, Churchill, who strives to modernize the farm importing technology from human society. Mr. Scotland, the Secretary General of 'Commonwealth Animal Realm' (CAR), has been able to convince the former farm owners in the Animal Region to grant self-governance to their farms, so the farms now are managed and directed by the animals themselves. However, Churchill has encouraged other governors in other farms to set up a new organization called 'Animal Production Economy Committee' (APEC) to protect the animals' rights as the producers and distributors of animal products. This has triggered a conflict of interest with CAR and its stakeholders, planning to replace Churchill with his critic, Muriel, the old goat, who has already started a new religion in the farm, called 'Animalism'.
With the aid of CAR and rats, Muriel is eventually able to sparkle an Animalistic Revolution in the farm and grasp the power, but soon after the revolution, CAR realizes that the 'Animalistic Republic of Animalia', as the Animal Farm was called after the revolution, has hostile attitudes towards human society and encourages Saddam, the governor of the neighboring farm, to attack Animalia. They fight the longest battle in the animal history and end in a stalemate, but the unrest resumes in the Animal Region through 'Animal Spring' through a series of engineered revolutions to topple the stubborn dictators in the farms.
Finally, Andy, a revolutionist's colt, hopelessly decides to flee the Animal Farm and surrender to his destiny in the human barns.
