 James works with young, hard-working farmer Frank Metcalfe, who has relocated from the city. Unfortunately his herd is diagnosed with brucellosis, which has both immediate and long-term effects. Tristan returns from school and admits to James that his exams may not have gone all that well. He also meets Richard Carmody, a brilliant veterinary student who is spending a few weeks with the practice to gain practical experience. Tristan takes a dislike to him and he and James look for an opportunity to teach him what it s really like to work in a country practice. Finally, the vets and the village doctor see an opportunity to teach Gobber Newhouse, a local bully and wife-beater, a lesson when he steps on a rusty nail and needs care.
