James Herriot interviews for a new job with Yorkshire veterinarian Siegfried Farnon, and his first day is one full of surprises.
Skeldale House descends into chaos with the arrival of Siegfried's wayward brother Tristan; Mrs. Pumphrey throws a party.
An ailing racehorse puts James to the test; Tristan faces a similar temptation; Siegfried angles for a client.
Tristan gives Tricki-Woo the spa treatment while James deals with Helen's champion bull; Siegfried comes to a decision about Tristan.
It's the Darrowby Show and James is 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.
The Dales are in the grip of a bitter winter; Siegfried has the flu and James's workload has doubled; Tristan pours over his textbooks to try and help his friend find a way to save the cow.
