Noel Fitzpatrick and his team return to provide more cutting-edge animal care, beginning with a dramatic emergency. Staffordshire bull terrier Lulu has been hit by a car and had her pelvis smashed into more than 25 pieces. The professor's only option is to pin the larger pieces back together in an operation that will require all his expertise. Noel and his team also treat a giant schnauzer called Florence who has a sore knee, and a pointy-eared Jack Russell called Muffin who has a mysterious problem with her back legs.
