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.

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.

The atmosphere is tense as James prepares to perform groundbreaking surgery. Meanwhile, Siegfried wrestles with a disinterested prize bull, and Tristan's hormones run riot over Darrowby's merry widow.

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.

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.

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.

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.

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.
