The young vets are now 18 months into their careers. Trude Mostue, Emma Milne and Joe Inglis each have a difficult case to deal with in their surgeries. Joe is attempting to remove an abscess from Gizmo the snake, a tricky enough procedure, but then his patient stops breathing. Trude has to remove a lump, too, which is attached to Wilbur the Vietnamese pot-bellied pig. Unfortunately pigs don't do well under general anaesthetic so it's a nerve-racking operation. And Emma has to open up a German shepherd dog who seems to have a large, chewed-up lump of carpet wedged inside her.
