Otis is a happy tractor who works hard on the farm. When a bawling baby calf joins the farm, Otis' "putt puff puttedy chuff" is the only thing that soothes her. Otis and the calf become friends, but soon Otis is replaced by a big, yellow tractor. One day the calf gets stuck in the mud - who do you think will save the day?
