It is birthing season in Michigan, which means Dr. Pol and his clinic staff have their hands full. After receiving an emergency calving call, Dr. Pol and Charles discover that a heifer is already in labor -- but is still out in the pasture. So before he can help her, they'll have to catch her! Meanwhile, Dr. Brenda gets an urgent call about a few sick piglets that were recently purchased for a 4-H project, and she must stop this potential pneumonia epidemic before it spreads even further.
