Peter operates on Wesley, a greedy terrier that has taken its food obsession too far and eaten an oven glove. Julian makes the difficult decision to remove the eye of Patch the rabbit, but an unexpected lump raises further concerns. Julian is then called out to help a ewe that is struggling to give birth to a large lamb. A makeshift operating theatre is set up in the barn, where he performs an emergency caesarean section, hoping to save both mother and baby.

The series concludes with an episode focusing on births and new beginnings. While delivering a calf, Julian also helps a new graduate to begin her veterinary career. At the Boroughbridge surgery, nurse Sally waits to discover if a labrador impregnated by her own dog has successfully conceived, and hopes to be able to take one of the litter home when they are born. Peter Wright is more concerned with preventing pregnancies, and has four cats to castrate in one day before they can go to new homes.
