As the clinic's 30th anniversary approaches, the Pols plan an old-fashioned pig roast after extracting a mouthful of porcupine needles from a dog and inseminating a cow, of course.

Dr Pol and his son Charles attend to a terrier with a mystery leg problem, and two cows with internal ailments.

As Dr Pol and Charles deal with herds of intractable farm animals, the older vet's energy impresses his son.

Two goats are among the patients, one may have been blinded when a horse kicked it in the head.

As if treating dogs for eating homework and injured pheasants weren't enough, there is a tornado storm warning forces the vet and his staff to retreat to the basement to continue there important work.
