Julian is called out to a desperately ill calf. Peter treats an elderly cat with severe constipation. Other patients include a young, wild stag trapped by its antlers, a dog with a dislocated leg, a postnatal cow and five noisy, young goats whose horn buds need removing.

Julian Norton has a large lump to remove from between a Highland cow's horns, then must find out why an event horse has broken out in lumps from head to hoof. Meanwhile, Peter helps a first-time mum deliver her lambs and treats a micro-pig who has outgrown his house and is under the weather.
