All Creatures Great and Small (1978)

S7E2 Knowin' How to Do It

Tristan finds himself in a bit of a pickle after accidentally injecting a farmer with an anti-abortion vaccine. Nat Briggs is furious, believing his hopes of starting a family have been dashed due to Tristan’s blunder, and he lurks around the Drovers, ready to confront him. Instead, it’s Siegfried who receives a letter hinting at potential legal trouble. Meanwhile, James keeps Helen on her toes, shrouding his trips to a nearby carpenter in secrecy, which raises her suspicions, especially since she knows the joiner's pet passed away not long ago.
