Looking at the work of `bionic vet' Noel Fitzpatrick. Oscar, a two-and-a-half-year-old-cat whose back feet have been chopped off by a combine harvester, is flown in in the hopes that Noel can give him two new feet, while the X-Men inspire Noel to come up with an extraordinary new surgical solution, dubbed `the Wolverine technique', for an arthritic Labrador.

Noel removes Charlie the Labrador's tumour and replaces it with a custom made implant that exactly mirrors Charlie's diseased bone, making him truly bionic: part metal, part dog. The survival of cross border collie Sasha is at stake as Noel sets about giving her a new bionic knee.

Noel engineers a specially-designed bolt and prepares border collie cross Sasha for her second major bionic operation. Plus, after being hit by a car, four-year-old cat Lottie is left with a shattered pelvis. Noel thinks he can reconstruct and rebuild it, but her owners only have a limited amount of insurance money.

Six-month-old puppy Ice has been rushed to Noel's referral centre having been trampled by a horse. Noel tries to reconstruct the dog's shattered leg as he battles the infection caused by the horse's hoof. There are concerns, too, for Gatwick sniffer dog, Neo. He's been compensating for a serious knee problem in one of his back legs and requires significant surgery. Plus, there's an update on Lottie.

There's no let up at the referral centre as the cases continue to flood in. Noel is presented with another major surgical challenge. Seven-month-old puppy Jolly has a painful bone deformity in both his front legs. His owner, Christine, agonises over whether it's fair to put him through an operation in which Noel proposes to use a new technique to treat the bone growth deformity.

Ianto, a nine-year-old corgi, has an infected cancerous growth which is eating away his foot. Noel decides that the only way to save Ianto's life is to amputate the diseased paw and give him a custom made prosthetic foot. We also find out whether the groundbreaking surgery to correct puppy Jolly's bone growth deformity has been successful.
