All Creatures Great and Small - Season 4 (1988)

Calum Buchanan joins the practice along with his tame badger, Marylin. Pregnant ewes, the plumbing at Sceldale and Helen's lost engagement ring herald the new arrival.

Tristan has been appointed a fertility counselor for the Ministry of Agriculture. He and James are sent to Grimbsby to examine an export consignment Russian vets. The Russian woman vet lives up to Tristan's belief that all Russian women are built like discus-throwers.

James has a crisis of professional confidence while treating a cow with a new drug. Tristan tries to convince a local farmer of the virtues of artificial insemination but Siegfreid only succeeds in enraging the farmer's bull.

James has his eye on a little semi-detached property coming up for sale, with the notion it would make a pleasant surprise for Helen. Unknown to him, however, Helen has grander ideas. There is trouble from a local farmer, which ironically leads Calum to celebrate his departure from the Herriot household.

The church fete looms for the Darrowby vets, along with the dreaded Scottish country dancing display. Can Tristan brush up his steps in time to woo the fair Deirdre? Or will his colleague Calum's back-to-nature approach sweep her off her feet?

James and Seigfreid deal with a sheepdog trainer, whose dog is suffering from epilepsy. At Skeldale, two wild cats wander in the garden and Helen takes out food for them. She is hopeful of keeping them but James warns her that they will never come in from the wild.

The week leading up to the Darrowby Show proves to be a difficult one for James. He finds that he has been asked to judge the dog section at the show, an invitation he can't refuse. Since Mrs. Pumphrey will inevitably want to enter Tricki Woo, James expects to be put in a very embarrassing situation.

Trying to save the life of a badly injured, much-loved cat, James and Tristan seek the help of Granville Bennett, who runs a small animal hospital. The fruits of Bennett's practice are clearly much richer than the hard graft of the Dales, and James is intrigued to find that Bennett is looking for a partner.

Andrew Bruce, an old school friend of James' comes to stay for a long weekend. Andrew, a city bank manager, is rhapsodic about the idyllic countryside and Yorkshire Dales courtesy, and he cannot understand why James should want to change such an ideal lifestyle -- until he finds himself in a rural nightmare.

Harvest Sunday proves to be a trying time for the practice. Seigfreid seizes the opportunity to teach Callum cleanliness by example, forcing him to watch "the perfect operation" on a sick cow. Unfortunately, the operation doesn't go according to plan. When Callum is chased by a bull, James goes to his aid.
