The first signs of summer are gradually creeping across central Michigan and Pol Veterinary Services is in full swing. Dr. Pol and Charles head to Gross Dairy Farm for an emergency call to help a feisty cow with a twisted stomach and a foul stench. Back at the clinic, Dr. Pol examines Ginger the goat and suspects it might have polio. Dr. Brenda receives an emergency farm call of her own -- a new heifer at Delbert Garrett's farm has a prolapsed uterus and is still straining post-labor.
