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 meets Richard Carmody. 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.
