Can Peter Wright help a young farmer who's inherited her farm from her late father? She's having a taxing day, with her sheep struggling to give birth. Matt Smith's latest unusual patients are father and son otters at 
the local zoo. Julian Norton operates on a much-loved Collie called Callie. When a rescue piglet has a badly torn ear, Rohin Aojula heads into the pig sanctuary in the woods. And it's even darker at the animal hospital in Huddersfield - all systems are down because of a power cut. But the vital surgeries have to continue, so how will the team cope?

1970s fever hits Julian Norton's practice in Wetherby! But at Cannon Hall Farm, Dave Nicholson's worried about a different kind of fever. A mystery illness has struck down their prized Swiss Valais tup Albert, and Shona Searson is worried it could be serious. Peter Wright's patient is a grumpy goose called Jemima, who has a nasty-looking eye infection. And a worrying problem interrupts a happy retirement for former sheep farming team Steve and Stomp, as Rohin Aojula can see that old Collie Stomp needs life-saving surgery.
