The fortunes of the hard-working Dalby family look set to dwindle even further until almost by accident James discovers the cause of their herd's illness. However, James still needs a push start on other fronts, and Siegfried and Tristan decide to remedy matters with their own expert advice.

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.

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.

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.

Siegfried is determined to make the errant farmers pay their bills.

Siegfried gives a friend's offspring some experience in the surgery. Calum initially resents this, but bucks up when he sees the young student.

Life at the Yorkshire veterinary practice continues to challenge the partners, whether by neglected animals or tight-fisted farmers. There are domestic challenges for Tristan, however, when James and Helen play a practical joke with a "Welcome Home" card from an old female admirer. Life is never simple when true love or the demon drink rule Tristan's life, and he is soon in trouble with Siegfried. A new housekeeper, Mrs. Alton, has been recruited by Siegfried to keep a watchful eye on Tristan, who, dispatched to tie up the details of her employment, is delighted to discover that Mrs. Alton is a rather attractive young widow. But this is not the Mrs. Alton that Siegfried had in mind.

Tristan's heart is all a flutter because of the lovely Jane Mercer. When he discovers that she sings in the choral society, Tristan develops a fresh interest in matters musical. But strong-willed Jane takes a donkey's owner to task for neglecting the animal, much to the embarrassment of Tristan. Farmer Biggins, meanwhile, baffles all three partners with his strange behavior. A legendary non-payer of vets' bills, he finally meets his match when Granville Bennett - "the finest small animal practitioner in the north" attends his tom cat and manages to get Biggins to settle his outstanding account in full.
