The animals of the world want peace on earth. To achieve this goal they call a big conference to which representatives of every animal species must attend. When the humans ignore their demands for peace through the abolishment of all weapons, the animals resort to drastic measures and kidnap all the human children.

They will release the children, but only when the humans meet all their demands. Curt Linda's animated film is an imaginative children's film masterpiece for young and old. Based on the book by Erich Kästner.
