Mr Tanner the farmer pollutes his farm and mistreats his animals, leading them to stage a rebellion. They build an intergalactic space rocket to take them up into the clean, clear skies, far away from those who are polluting the planet. First a chicken, then a clever rabbit, and lastly a calm sheep, are chosen for test flights. But each time something goes wrong and the rocket returns to Earth. The animals don't know what to do. But then Farmer Tanner discovers the rocket and, determined to take it for his own, he zooms off into space, and is never seen again.
