Set in the 1930's, young vet James Herriot arrives in the village of Darrowby in the Yorkshire Dales hoping to land his first job with established veterinarian Siegfried Farnon.

James is on pins and needles awaiting the results of the postmortem on Lord Hulton's horse. He continues to make his rounds, becoming acquainted with some of the local remedies for sick cattle. Siegfried's younger brother Tristan returns to Darrowby from veterinary college having once again failed his exams. Siegfried assigns him to collecting payments on market day, but where has he put the receipt book? James is also introduced to Mrs Pumphrey and her pekingese, Tricki Woo, who then sends Uncle Herriot a gift.

James visits the Alderson farm to treat a calf with a broken leg and meets the very attractive Helen Alderson for the first time. Meanwhile, Siegfried decides to bring to some business-like discipline to the practice by hiring a secretary, Miss Harbottle. Not surprisingly, she turns out to something more than he expected!

James continues to pine for Helen and learns he has a rival for her affections in the form of Richard Edmundson, a wealthy member of the local gentry. Tristan suggests James may want to join the local musical society - especially since Helen is a regular attendee. Tristan has another all-nighter with the bell ringers, leading Siegfried to believe he has too much time on his hands. So he puts him in charge of some newly acquired piglets. Mrs. Pumphrey also acquires a new pet pig, Nugent, and she asks Uncle Herriot to examine him. Siegfried reaches the breaking point with Miss Harbottle.

Having finally worked up the courage to ask Helen out on a date, James is not quite sure where to take her. Tristan convinces him that the first date is always the most important so he recommends that James take her to dinner at the Reniston, the poshest hotel outside of London. To his chagrin, James follows Tristan's advice and the date isn't very successful. To make matters worse, Tristan subsequently gets James to complete a foursome with two lively lasses and they meet Helen and Richard Edmundson in less than ideal circumstances. Tristan is less than enthused at having to care for the pigs Siegfried has acquired. James treats an itinerant family's sick horse. The vets seek the assistance of Sister Rose in finding a home for a stray dog.

Helen visits the surgery with her dog Dan, but James is embarrassed by his performance when he last saw her at the dance. He nonetheless manages to ask her out to the movies, but once again, their date is a bit of a disaster. The film he thought they were to see has been replaced by a cheap western and Gobber Newhouse, in his cups, provides a bit of unexpected entertainment. Tristan reads with interest in the local newspaper that there may be a historical basis for the ghost that haunts Raines Abbey, given that several monks were killed there several centuries ago. Sure enough, the ghost soon makes another appearance. James has to deal with a farmer who insists his cow was struck by lightning and wants James to provide the necessary documentation to support an insurance claim. Siegfried lectures James and Tristan on their forgetting equipment during their farm visits; of course, Siegfried needs to listen to his own advice.

James offers his condolences to Mrs. Dalby whose husband recently died. He's a bit doubtful when she tells him that she'll be running the farm on her own. Things go from bad to worse when some newly acquired cows fall ill. Helen stops by the surgery and invites James to tea on Sunday. James gladly accepts and things are going well until one of Mr. Alderson's cows falls ill and James is unable to save it. Helen and James manage to overcome their bad luck however. Tristan finally gets a car to use but accidentally releases the parking brake; the car goes roaring downhill and straight into the new golf course clubhouse. Gobber Newhouse convinces Jim to have a drink with the lads, only to also present him with the bill.

Tristan and Siegfried have to treat Clancy, Mr. Mulligan's very large dog who is "womittin" again. Mrs. Hall advises James to get on with it vis-a-vis Helen and warns him that he risks losing her, with Richard Edmundson around. James however thinks Helen's father doesn't think much of him and that overall, he's a very poor catch. Siegfried and Tristan are also concerned that James is too slow getting off the mark and decide to do something about it. James finally pops the question, but shudders at the thought of having to ask Mr. Alderson's permission. Mr. Biggins entertains the lads at the Rovers, courtesy of Tristan. Mrs. Dalby is worried about her herd of cattle and James can't come up with a diagnosis.

Tristan and James treat Mr. Pickersgill, a good farmer with a tendency toward malapropisms. Tristan has an injury while there, but finds an immediate remedy. Siegfried is called out to the Sidlows, who are a bit difficult. Tristan gives James advice on his honeymoon plans and suggests a Mediterranean cruise. James couldn't possibly afford it and Tristan suggests he try his hand betting at the track. Siegfried is invited to the Broughton races and he knows the racing circuit is looking for a new vet. Once there however he meets an old friend, Stewie Brannon, a fellow vet whom he's not seen for many years. Siegfried faces a dilemma when the Agriculture Ministry requires the practice to undertake tuberculin testing the same week of James and Helen's honeymoon. James proposes a solution. Siegfried's wedding gift surprises James.

James and Helen are on their honeymoon and start the tuberculin testing. They're staying at a local inn but are constantly interrupted by the landlady. Back at the practice, Siegfried is particularly harried and Tristan announces that he must return to Edinburgh to take his final exams. He nonetheless decides to help Tristan prepare. James is concerned with the generosity of Siegfried's wedding gift. James meets Angus Grier, a nearby vet, and his student Clinton. Grier invites James along on a call and provides him with a peculiar change of clothes. Siegfried suggests that they hire a student while Tristan is away.

James works with young, hard-working farmer Frank Metcalfe, who has relocated from the city. Unfortunately his herd is diagnosed with brucellosis, which has both immediate and long-term effects. Tristan returns from school and admits to James that his exams may not have gone all that well. He also meets Richard Carmody, a brilliant veterinary student who is spending a few weeks with the practice to gain practical experience. Tristan takes a dislike to him and he and James look for an opportunity to teach him what it's really like to work in a country practice. Finally, the vets and the village doctor see an opportunity to teach Gobber Newhouse, a local bully and wife-beater, a lesson when he steps on a rusty nail and needs care.

Tristan finally gets the bad news he's been expecting: he's failed his final exams and must now tell Siegfried. He decides to soften up Siegfried a bit starting an exercise program and cutting out drinking and smoking. James has to deal with Mrs. Donovan, a self-styled animal healer whose dog is killed in an accident. When he's called in by the local constable to deal with a case of animal cruelty, he knows just who to call on to find it a home. Finally, James must assist cranky Angus Grier, a neighbouring vet who has a broken arm.

It's a bad time for the vets and a local farmer when they discover a case of foot and mouth disease. The farmer's stock must be destroyed and a general quarantine is in place for thirty days. Siegfried, who came into contact with the animals confines himself to Skeldale house, meaning James and Tristan must do all of the outside calls. James discovers the power of anesthesia in assisting animals to heal: first with a farmer's dying ewe and then with the Flaxton's pet poodle.

The waiting room is packed at the Darrowby practice, but Siegfried seems more focused on catching his hard-drinking brother asleep on the job.

The return of lambing season brings a boost to Siegfried's spirits, but James, laid up in the surgery, is reminded of the harsher realities of a vet's life.

Nerves are frayed as Tristan's encounter with an "exploding" bullock leads to a lawsuit, and Siegfried's venture in guinea raising runs foul. Meanwhile, James is sent to assist "on of the biggest boozers in the business."

As the tractor threatens to do away with a way of life in the Dales, James battles to save a dying shire horse.

The Darrowby Show is a much-anticipated event for the whole community, except for the duty vet. This mixed honor falls to James this year.

While James struggles to cope with the procrastinations of the Bellerby family, Tristan succumbs to the charms of a millionaire shipbuilder's daughter with a penchant for lobster.

James gets a taste of the high life when he comes to the aid of a city vet, Granville Bennet, while Siegfried juggles the care of Mr. Wilkinson's awesome "colt" with the fine art of debt collecting.

James becomes suspicious when the Farnon brothers -- usually keen cricketers -- "volunteer" him in their stead for the annual cricket match between Darrowby and Rainby.

Tristan may have finally found the right girl in Alice McTavish. Meanwhile, James struggles to save a dog whose death could trigger the end of the owners' marriage.

James concludes that the drawbacks of a vet's life -- long hours, fierce dogs and a cunning sow named Prudence -- pale in comparison to the rigors of making a speech to the Darrowby Youth Club.

Siegried turns on the charm to teach Tristan a lesson, while James, busy with calving, finds one farmer's traditional Yorkshire hospitality a bit hard to swallow.

Despite Siegfried's insistence that he relax and "cultivate the inner man," James can't shrug off the irritations that often make his professions a dog's life. Siegfried's inner man is cramming for the annual quiz that pits the men of Darrowby against the fearsome Women's Institute.

Christmas at Skeldale House can be a formidable undertaking, what with sick foals, overfed dogs and a skeleton guarding Siegfried's secret hoard of goodies.

James is busy with tuberculin testing but is summoned to the Ministry of Agriculture when the test results don't quite add up. Siegfried has to deal with a dog owner who only believes in strict discipline in dealing with his dog. He also has to deal with dying sheep, but the owners may not have the means to save them. Helen gets a job as a secretary, but James isn't quite sure he approves. Siegfried, on the other hand, thinks it's a wonderful idea. Tristan is less than enthused however when he realizes he will have to take over Helen's duties in the partnership. Mrs.Hall tells Siegfried that she has to leave to help her brother, who is now alone to work his farm.

Siegfried bumps into Mr. Beresford, the manager of the local bank whose dog behaves badly in the car. Tristan woos the lovely Marjorie Simpson and Siegfried meets Sarah Raworth. James treats the elderly Mr. Bailey's dog who has developed a bad case of bronchitis and Siegfried criticizes James when he waives the fee. Siegfried, however, has trouble following his own advice. Tristan rescues a severely injured cat and then convinces James to treat him rather than put him down. Helen promptly adopts him and nurses him back to good health but is devastated when she learns the cat belongs to the Gibbons family. Everyone celebrates Tristan's birthday.

Mr. Biggins tells James about his cowhand, Ned Finch, who goes drinking every night and is drawn to the bright lights of the big city. All James ever sees is an amiable fellow having a quiet drink in his local pub. Mrs. Hall is all aflutter with the visit of Mr. Barge, the loquacious pharmaceutical representative. Mrs.Pumphrey is worried when her new boxer, Cedric, proves to be overly flatulent. James finds a perfect solution. Mr. Beresford's dog is still misbehaving in the car. Siegfried suggest a new sedative, but it unfortunately doesn't have the desired impact.

Tristan and Siegfried meet Roddy, a hobo and his dog who are passing through the area. Mrs. Hall needs to visit sick relatives for a few days and Tristan is assigned chief cook and bottle washer. He also has to do the spring cleaning, cook the meals and put in his time in the surgery. Siegfried is less than sympathetic when Tristan complains. Granville Bennett stops in wanting the vets to care for his dog, Phoebe, who needs an minor operation. He invites James and Siegfried to lunch the next day and James once again over imbibes. Helen practices her first aid skills on James.

Tristan has had a rather late night and Siegfried takes him to task over his bad habits. Tristan announces that he has a steady girlfriend, Deborah Mount and will reform his wild ways. Turns out Deborah's father doesn't know anything about the relationship and may not approve. When he does hear of it, he has serious doubts about Tristan's character. Tristan doesn't help his case with his silly pranks. James has several encounters with a street urchin, Wesley Binks, whom he'd earlier caught stealing. James nonetheless helps Wesley out when his dog contracts distemper. Siegfried reacts badly when the Weeting brothers tell him they are off to join the military.

James and Helen are about to celebrate their first wedding anniversary and Tristan suggests to James that they go to the Harlequin, a modest restaurant that opened recently. It turns out to be anything but and is in fact one of the poshest restaurants in the area. Siegfried starts seeing Margery Egerton. Tristan, now a free man since being forbidden to see Miss Mount, sets his sights on previous conquests. Siegfried and Tristan ask James to arbitrate when they both want the same evening off. James has to pay several visits to Mr. Bailes whose dog seems to take great delight in scaring the wits out of him.

The possibility of war is on everyone's mind with Helen preparing for the privations ahead and Tristan tasked to tape the windows in the event of bombing. Siegfried decides that they should conserve food and heating by eating their meals together, but Mrs. Hall takes his instructions to economize a bit too seriously. James treats Hamish, a sick dog who requires an operation and Tristan, who is tasked with overseeing his recovery, loses him. The vets forgo a posh evening out to treat a stray dog who has had an accident. Tristan is aghast at Siegfried's attempt to pair him with Deirdre Headingley, one of his crony's less-than-attractive daughters.

The vets visit a modern dairy farm and are left to wonder who benefits from the cold efficiency. Miss Westerman returns with her dog Hamish and Tristan tries to avoid her, given that he misplaced her dog the last time she him in the vets' care. She is concerned at the rumors that all dogs will need to be destroyed if war is declared but Tristan sets her mind to rest. The vets agree to spay a cat for a minimum fee, but find they may have gotten more that they bargained for. Siegfried treat Herbie Hinchcliffe's aging horse Dolly and becomes emotionally involved in the case when he has to put

Siegfried has become a bit horse shy given his recent experience with Dolly. James has to deal with the very unpleasant Ralph Beamish, an arrogant horse owner who continually ignores his advice. Siegfried visits a local pig farmer and fears his animals may be infected with foot and mouth disease. Mrs. Beck continues to complain about her with the vets bill and is now worried about how her cat might survive a gas attack should war be declared. Germany has invaded Poland and the British government has given Germany an ultimatum to leave or they will be at war.

Mrs. Hall is away visiting a cousin and James agrees to fill in for Stewie Brannon while he's on holidays. Siegfried and Tristan make the best of it but Tristan's culinary skills have not improved over the years. He does make an excellent bangers and mash, for every meal, everyday. James treats a severely injured dog and has a bit of difficulty with the local dialect.

The Darrowby Bell Ringing Society is suspending its operations for the duration of the war and they have one, final "meeting" at the local pub. James and Tristan go to the bell tower with not unexpected results. The vets have to deal with a series of dog poisonings. They soon identify the farmer responsible, but not before several more animals die. Siegfried treats Joan Clifford's dog Saxon, but the case has very specific implications for her. James treats Mr. Hanson's pigs but it's Mr. Hanson who is most entertaining in that he always speaks at the top of his lungs.

James treats Paul Cotterell's dog Theo, who has been losing weight and is diagnosed with Hodgkin's disease. James recommends that Theo be put down and Paul agrees. James doesn't realize the impact this has on Paul and the tragic results that ensue. James meets Lord Hulton, a hard working farm owner despite his aristocratic background. Hulton takes a liking to a horse that has wandered onto his property from the nearby military depot. At the Billings farm, James finds young calves who are wasting away. He thinks they have ingested an irritant of some kind, but the vets simply can't isolate it.

Siegfried takes Tristan to task for not mending a hole in the fence. Tristan announces that he now refuses to subject himself to Siegfried's tyranny but he is given 24 hours to mend the fence or face the consequences. Tristan tries to recruit James in his battle with Siegfried, but James will have nothing to do with it. Siegfried comes up with the perfect response. James operates on a sick calf but those assisting him are worse off than the calf. As a result, James comes down with a bad case of the flu. James is also concerned at having to give bad news to Andrew Vine about his dog, given his recent experience with Paul Cotterell.

England is at war and the time has come for James and Siegfried to join their military units. Their last day at the practice is a busy one and James is repeatedly called out when he had hopes to spend a last, quiet evening at home with Helen. Siegfried surprises James with a small gift. Mrs. Hall also has a surprise announcement for everyone and Tristan receives shocking news from the Royal College of Veterinary Surgeons.

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.

The week leading up to the Darrowby Show proves to be a difficult one for James. He finds that he has been asked to judge the dog section at the show, an invitation he can't refuse. Since Mrs. Pumphrey will inevitably want to enter Tricky Woo, James expects to be put in a very embarrassing situation.

Trying to save the life of a badly injured, much-loved cat, James and Tristan seek the help of Granville Bennett, who runs a small animal hospital. The fruits of Bennett's practice are clearly much richer than the hard graft of the Dales, and James is intrigued to find that Bennett is looking for a partner.

Andrew Bruce, an old school friend of James' comes to stay for a long weekend. Andrew, a city bank manager, is rhapsodic about the idyllic countryside and Yorkshire Dales courtesy, and he cannot understand why James should want to change such an ideal lifestyle -- until he finds himself in a rural nightmare.

Harvest Sunday proves to be a trying time for the practice. Seigfreid seizes the opportunity to teach Callum cleanliness by example, forcing him to watch "the perfect operation" on a sick cow.

With Helen still bedridden, there is a dramatic increase in domestic chaos. While James struggles manfully with both chores and children, Siegfried and Tristan praise his noble efforts -- and do precisely nothing.

The romance between Calum Buchanan and Deidre McEwan flourishes. Siegfried has been hoping that the love affair 5 would quiet down but instead it seems to be going full blast.

Life at the Yorkshire veterinary practice continues to challenge the partners, whether by neglected animals or tight-fisted farmers.

Queen Elizabeth II's Coronation is cause for Darrowby celebrations on a grand scale. James and Helen's 12-year-old daughter, Rosie, is due to be crowned, too -- as Darrowby's pageant princess -- by her reluctant elder brother, Jimmy. But a severe cough could put a fast end to her starring role in the festivities. Helen is keen to try Mrs. Alton's herbal remedy, but James tells her to give penicillin a chance first. Siegfried also resorts to traditional cures when he tackles a sheep with liver fluke, and is all too eager to pass on to James a rather smelly problem afflicting a dog called Wolfie.

Buffoon Stewie Brannen, an old friend of Siegfried's, has invited the distinguished Professor Norton to a black tie dinner, and prevails upon Siegfried to host it at Skeldale -- and lend him a dinner suit.

Siegfried takes a close friend to task for wasting his own talents as a veterinary surgeon. Ewan Ross -- "the best horse man north of the Humber" has let his career slide gently into the whiskey bottle after the death of his wife. But Siegfried is determined to make use of his considerable skills. A valuable racehorse with a strangulated hernia could provide Siegfried with not only a way of striking back at "vets in Bentleys", but also putting Ewan on the straight and narrow.

Mrs. Clarke, a very determined old lady, is struggling to keep her farm running until she can hand it over to her young granddaughter, Mary. But she is reaching the stage when she can no longer handle the pressures, even with her elder granddaughter, Katherine to help -- and Katherine is planning to pursue a nursing career in Africa...

James and Tristan find themselves embroiled in an argument between David and Johnathan Bradley who are competing for the honour of ringing the Christmas bells.
