In case of emergency, dial Dr. Pol! The stakes are high for Dr. Pol and the clinic staff as animals across central Michigan find themselves in one complication after the next. Dr. Emily rushes to treat a dog that had been shot, and then responds to another call involving an injured Beagle. Meanwhile, Dr. Pol and Charles get roped into an unexpected rodeo that puts Charles out of commission.

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.
