Skeldale House descends into chaos with the arrival of Siegfried's wayward brother Tristan. Helen provides James with a reason to stay in the Dales.

Tristan sets about collecting debts owed to the surgery and takes a shine to Maggie, the new barmaid at The Drovers. Siegfried hopes to bag the job of Attending Vet at Darrowby Racecourse, by buttering up the head of the race course, General Ransom. When the favourite to win on the race day is diagnosed with a inoperable condition, James has his first painful experience.

James is forced to take in Mrs Pumphrey's pampered Pekingese. Tristan prepares to return to university, but needs Siegfried's help to pay for his accommodation, but Siegfried insists he must first prove he is serious about being a vet. James treats the Aldersons' prize bull, and Helen rewards his efforts with some unusual home baking.

It's the Darrowby Show and James is pleased as punch that he has been given the honour of Attending Vet. But Siegfried and Tristan know the job is a poisoned chalice and reckon James won't last the day without throwing in the towel.

James' workload doubles when Siegfried takes ill during a harsh winter. Mrs Hall discovers it is James' birthday, and Tristan tries his best to cheer him up by arranging a double date. Season finale.

James is trying to bury his pain over Helen and has invited his new girlfriend Connie to the annual Skeldale Christmas party. As the house fills with locals, James receives a call from a man who wants help with his dog who is giving birth.
