All Creatures Great and Small (1978)

Season 7: Episode 2

Planting a syringe full of anti-abortion vaccine into a farmer's backside creates something of a crisis for Tristan. Farmer Nat Briggs is convinced that his chances of starting a family have been ruined by Tristan's clumsiness, and he hangs threateningly around the Drovers waiting for a chance to confront Tristan. But it is Siegfried who gets a letter threatening court action. James, meanwhile, keeps Helen guessing about his mysterious visits to a local joiner, whose pet, Helen knows, died some time ago.
