As late spring turns to summer, one thing remains constant at Pol Veterinary Services - the vets are busy with patients in need. Dr. Pol, Dr. Brenda and Dr. Emily shift into overdrive to meet the needs of their clients, until some extra help arrives. The Pol Clinic veterans take a new vet, Dr. Erin, under their wing, as they flip cows, clamp calves, tube horses, and treat a rescue rooster.
