From the Internet:
The animals of Manor Farm are unhappy, in fact, downright angry. Jones the farmer is a brute and not even a good farmer. Led by the pigs, who are the cleverest and most persuasive, they rise up and stage a revolution. They plan a future for the good of all animals, all for one and one for all. They run the farm themselves, they struggle through the hard times and battles to retake the farm, they weather the internal political struggles of the pigs who cannot agree who should be leader, and in general make a better life for themselves. Then disaster strikes. The pigs seem to be changing the rules to suit themselves and have ways of frightening those who speak out. The one pig who really had a good heart is ousted by the bad pigs. The dream turns into a nightmare, will it all end in tears?
