Dr. Pol is fielding farm calls all over Isabella County now that the spring birthing season is in full swing. Dr. Pol is ready to catch whatever curveball a cow throws his way, but when the local minor league baseball team asks him to throw the first pitch, it comes right out of left field. He may not be a baseball pro, but Dr. Pol knows how to play hardball, and after practicing with Charles, he's going to show Michigan a first pitch to remember. But practice comes last when Dr. Pol still has so many farm calls to deal with first!

The Isabella County Fair is just around the corner – which means Dr. Pol, Dr. Emily and Dr. Brenda are busy treating fair animals, making sure they are in tiptop shape for competition. Dr. Pol and Charles start the day tending to a fair pig, whose future isn't looking so fair after all. Will Dr. Pol be able to get this prolapsed show pig back in shape? Across town, Dr. Emily's up to bat, with a cow named Toro – who's abdominal hernia seems to be more than a hiccup on the road to winning the blue ribbon. Now it's Dr. Brenda's turn – there are two horn-y things on the heads of steers, Big Ron and Hannah, preventing them from getting fair-side.
