Six school kids chosen from a pool of a thousand applicants find out if they have what it takes to become a vet. The group are faced with testing a lonely horse for a life-threatening illness.

With one day's experience under their belts, the Junior Vets are faced with Stella the dog, who is in need of an operation after being injured in a car crash.

The junior vets look into Kira the mare's heart murmur, and attempt to mend Gandalf the falcon's lumpy foot.

Morgan attempts to keep focus as the team try to figure out Benji the dog's painful pee problem. Meanwhile, Lauren travels to the farm to help a calf with a hernia.

The Junior Vets are challenged when a young pony who arrives in a lot of pain. Plus, see what will happen when they test homeless cat Finbar for a deadly disease.

The vets are kept busy and run off their feed from some very sick penguins; the vets have to work out what's wrong with a sick Boxer Dog called Caspar.
