All Creatures Great and Small

When Jimmy's Christening day is interrupted by the arrival of a surprise visitor, Siegfried makes a promise he struggles to keep, while a furry friend helps Helen to find common ground with James's mother.

Tristan settles into life back at Skeldale, but Carmody has taken his bed - and his brother! Mrs Hall schemes to bring the boys together and sends them to Pumphrey Manor after an alarming report of an escaped animal from the matron of the army convalescent hospital. Meanwhile, James hopes to reassure a worried Sid Crabtree when he's called out to treat a sick cow. 

Carmody gets outstanding exam results and is offered a position in a research program in London but he wants to turn it down so that he can stay at Skeldale where he can support the war efforts as a vet. Siegfried is relieved but worries that he might be holding Carmody back.

An exhilarated Mr Bosworth summons Mrs Hall to examine a piece of debris dropped from a plane into a remote field - this could be his hero moment. Doris arrives at the surgery with a poorly ferret for James to treat. Carmody finds himself oddly unable to string a sentence together in front of her.

Siegfried and Carmody meet the glamorous Miss Grantley and her herd of pygmy goats. Two are particularly hyper-sensitive and the vets must figure out the issue. There's a spark between Siegfried and Miss Grantley, who makes him realise that Carmody has to make the right decision about his future.

Meanwhile, what Bosworth thinks could be an explosive turns out to be something far less sinister. But Mrs Hall struggles with Mr Bosworth's overzealous reaction to the incident.

Siegfried encourages Carmody to take the offer but Carmody doesn't want to say goodbye to Skeldale. James treats Doris's ferret, and Helen realises that Doris's rat poison could have been behind a previous incident. Carmody finally makes a decision about his future and Mrs Hall and Bosworth mend their relationship.

James starts to behave very out of character whilst examining Tricki and his health takes a turn for the worst. Helen rushes him to bed, leaving Jimmy with Mrs Pumphrey and an already overburdened Mrs Hall, who is making strawberry jam for the WI. Meanwhile, Siegfried, needing an extra hand in Carmody's absence, recruits a reluctant Tristan to help.

When Siegfried and Tristan treat a Scuffling horse for a simple rash, something rather unexpected happens. Things go from bad to worse when their car breaks down. Tristan and Siegfried start to walk home, swigging from homemade wine gifted to them by Dobson. Old tensions between them simmer as they try to figure out the best course home.

Meanwhile, back at Skeldale, James drifts in and out of reality, hallucinating. Believing that he's back at RAF Abingdon, James's sadness surfaces and expresses his guilt that his comrades suffered and he survived. Helen is worried for James but, as he opens up to her more, she reaches a new understanding of what he's experienced.

Mrs Pumphrey finds herself fulfilling something of a new role and Mrs Hall holds everything together.

Now giddy from the homemade wine, Siegfried reveals how things went south with Miss Grantley and is secretly pleased when Tristan insists she'd be lucky to have him. Siegfried and Tristan come to a new understanding about their wartime experiences and, arriving in Darrowby, find some fun together too. James apologises profusely to Mrs Pumphrey, who catches Siegfried in a compromising position.
