Plot summary
The local rabbits have been much help to the Bean animals, so it is a surprise that some are vandalizing and stealing. Confronted, instead of apologizing, a rabbit criticizes Mrs. Bean, then gives ridiculous evidence that her husband was eaten by the Beans. Freddy and Jinx the cat investigate, discovering that the Grimby house in the woods next to the farm is used for political meetings. The speaker, inside a mechanical man that amplifies and distorts his voice, encourages the animal assembly to be "free" of humans. Freddy guesses their foe Mr. Garble is behind it. The A.B.I. (Animal Bureau of Investigation) is alerted to watch.
Freddy’s friend Mr. Camphor is asked to run for governor. This does not suit him ("I could sound like a fine governor, if I didn’t have to do any governing." p. 32). Camphor asks Freddy to visit the political meeting at his mansion, to say bad things about Camphor’s suitability. The pig, in his disguise as Dr. Hopper, invents faults, including that Camphor giggles in church and during speeches. But the political committee manages to see the bright side of these faults.
Money was stolen, and Mr. Bean’s handkerchief found at the crime scene. Since Mr. Bean’s laundry was stolen by rabbits, Freddy suspects a plot to organize animals against humans, telling lies that might be eventually believed. Miss Anguish, Camphor’s sister, is one of the guests. Her thinking is spacey, but it may be an act. She states that Freddy is a Hollywood film director. (So now Freddy is dealing with three odd sorts of thinking at once.)
Freddy tries convincing the committee again that Camphor is an unsuitable candidate: He proposes that all animals be given the right to vote! While the committee is deliberating, Freddy investigates the money theft.
Before he can collect evidence, Mr. Bean is jailed. Camphor joins the local Indian tribe to hide. Jinx discovers Simon the rat has returned, and with Mr. Garble is encouraging all animals to revolt and take control of farms from humans. To infiltrate the group, Jinx determines to pretend he has joined the revolution.
Freddy and Camphor’s butler, Bannister, are unable to convince Camphor to return; he has disguised himself as an Indian. The A.B.I. discovers the hideout where Garble is managing the revolution. They capture him, and smash the mechanical man used to make speeches.
It is too late to stop the revolution, however. Farms are taken over, including the Bean farm, which is then run by Jinx. Since the Bean animals do not know Jinx is undercover, he takes considerable abuse. To strike at the revolution, Freddy gets the cooperation of the captured Garble by convincing him that the Indians will burn him at the stake. Then Freddy turns to Simon, and for a while follows Jinx’s lead — only to trick Simon into sitting a cage disguised as a throne. With Simon out of the way, Camphor decides to appeal directly to the animals of the revolution, promising them the right to vote — which will make them the equals of people. This strikes a chord, and the revolution falters. Employing the aid of the dogs, who have generally stay loyal to their human masters, the farms are gradually recovered.
Garble escapes. He captures Freddy, Miss Anguish and Jinx, holding them for ransom. Miss Anguish tries to confuse their captors, but finally in desperation they set a fire to attract attention. Garble is recaptured and sent to prison. Simon and his criminal family are packed in a crate that is indefinitely shipped from place to place. The revolution fails. With the animal vote, Camphor becomes governor.
