Peter Wright heads to see his friend's sheep who are suffering from a nasty virus which has given them swollen faces and can be passed on to people. Before Peter treats the flock, he has to round up the rebels in the field.

Peter Wright performs emergency surgery on a greedy spaniel with a history of eating clothes, and Shona Searson rushes out in the night to save a cow who's having serious problems after giving birth. A newborn lamb with eye trouble needs Rohin Aojula's help. Also, Matt Smith and Julian Norton head to the coast to operate on a zoo's miniature donkey.
