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?
