When Madame Adelaide Bonfamille leaves her fortune to Duchess and her children—Bonfamille’s beloved family of cats—the butler plots to steal the money and kidnaps the legatees, leaving them out on a country road. All seems lost until the wily Thomas O’Malley Cat and his jazz-playing alley cats come to the aristocats’ rescue.
A lawless poacher wants to capture a majestic and rare golden eagle, so he kidnaps the boy who knows where to find the bird. Not to worry -- the Rescue Aid Society's top agents, heroic mice Miss Bianca and Bernard, fly to Australia to save the day. Accompanying the fearless duo are bumbling albatross Wilbur and local field operative Jake the Kangaroo Rat.
