A newborn lamb is brought to the hospital after being found abandoned by the roadside, and Matt and David have their work cut out to save its life. Elsewhere, Peter performs delicate surgery on a rat with a large tumour, and later, Julian's bank holiday barbecue is interrupted by a horse with suspected colic.

After enjoying a relaxing cycle into work, Julian faces an uphill struggle at the Thirsk practice. A Large Munsterlander has a cancerous tumour on his jaw, and another vet has already recommended having him put to sleep. Can Julian offer any hope?

Peter's also on his bike, as he gears up for a 170-mile cross country challenge, as well as trying to help a red deer with a face abscess.

Matt meets a cow who's struggling to walk on a badly swollen knee, and David visits a rookie sheep farmer who has a poorly ram. But the bigger concern is that Blueberry might have made Muffin the ewe pregnant.
