All Creatures Great and Small - Season 6

In the first episode, it's May 1945 and James visits Archie Tredwell's farm to help with a difficult lambing, with the ever-curious young Jimmy in tow. However, the farmer's beloved sheepdog Fly soon requires James's attention when she has a nasty fall. Archie notes a big stray dog that's been seen around the area, known to the locals as the ‘Barghest'.

Back at Skeldale, James realises that Fly has arthritis and might not be able to work for much longer, leaving the younger sheepdog Lad to step up. Tristan arrives home from his posting in Italy to find the house in all kinds of chaos! Tristan's perturbed by Siegfried's behaviour and James explains what a nightmare he's been.

James and Tristan head out of Darrowby to find the only person who can help – Mrs Hall.

James and Helen are now living at Heston Grange with the children. Helen is concerned about the state of Skeldale and Siegfried, but doesn't approve of James's plan to fix it.

When the vets are all out looking for Archie's flock of sheep James gives Siegfried some home truths. However, is it too late for Siegfried to get his act together?

James is exhausted running between Heston and Skeldale, and to make matters worse, he's often finding himself on the wrong side of Richard Alderson - this time, Richard's got a bee in his bonnet about the muddy floor. Meanwhile, Mrs Hall and James are curious about what Siegfried's been up to when James finds him wandering home after a night out.

James visits a local nurse, Sister Rose, to tend to one of her rescue dogs, and ends up agreeing to buy an X-Ray machine from the hospital, hoping that it will benefit the surgery, but he hadn't taken into account Siegfried's reaction, nor the problems it would bring to the house! He enlists Tristan's help to fix things.

Siegfried visits a concerned Mrs. Pumphrey, who fears that Tricki is giving her the cold shoulder. Meanwhile, in Darrowby, Mrs. Hall is perplexed by the odd behaviour of some of the locals and Helen wonders if Siegfried's behaviour in her absence might account for it. Mrs. Hall has to have a delicate word with Siegfried to try to put things right.

When Sister Rose's dog worsens, James is put through his paces to attempt to save him.

Richard is forced to eat his words when he realises that he's been wrongly accusing James all along. Helen has some news to share about her sister, Jenny.

Meanwhile, Mrs. Pumphrey reveals her hopes for Tricki's future to Siegfried – can she breed the next generation of Tricki's from him before it's too late?

A memorial service is held in Darrowby to honour the war's fallen soldiers and Tristan tries to hide his emotion. He's keen to go for a drink with Siegfried, but finds himself at the bottom of Siegfried's priorities, especially now Siegfried has a ticket to a coveted concert at Orley Castle.

‘Captain Farnon' is requested at the new and prestigious Beauvoir stables and everyone's confused when both Tristan and Siegfried arrive to tend to the horse, Philbrick. A disgruntled Tris isn't about to back down and give Siegfried the case, especially as Philbrick is owned by the enchanting Charlotte Beauvoir, daughter of the General. A hilarious rivalry between the Farnon brothers ensues and Tristan becomes suspicious of Siegfried's motives.

Meanwhile, James tells Mrs. Pumphrey not to give up hope in her quest to find a mate for Tricki, and James plans a date night to get some time with Helen, but first has to conquer the hills of Darrowby on an alternative mode of transport to appease Mrs. Pumphrey.

Charlotte Beauvoir is bemused as the vets offer differing opinions and Tris learns that they share something in common.

Meanwhile, Mrs. Hall stumbles upon a secret that Tristan has been keeping all this time and has to tell Siegfried.

Helen is thrilled when Jenny gets exciting news and sets about getting her sister prepared for a big move, but soon realises neither of them are ready for it. Mrs Hall asks for time off for her granddaughter's birthday in Sunderland, and Siegfried starts to panic.

James is worried about the practice finances but it falls on deaf ears when he tries to discuss the matter with Siegfried. James decides to take on the role of attending vet at Hensfield dog track to earn extra money.

Tristan visits Mrs. Ainsley who has an aggressive parrot called George. Tristan fears the parrot may have a contagious disease and takes it back to Skeldale for observation, but the parrot starts to have an impact on his personal life.

James arrives at Hensfield Racetrack and is put to work straight away, checking over the whippets. However, he soon wonders if there is something else afoot.

Maggie uncovers one of Mrs. Hall's hidden talents and Siegfried enjoys spending time with Jimmy - until Jimmy inadvertently tells him some home truths.

VJ Day is announced and Mrs. Hall helps to plan the celebrations. Tristan leans on his brother when his past experiences come home to roost. James is puzzled by the disappearance of a newborn calf.
