Kate Humble and Ben Fogle return to Longleat Safari Park to join the keepers and animals as the park springs into action for another season. The keepers get a shock when three highly endangered cheetah cubs are born, the first in the park's history. There is also a catch-up with Anne, the rescued circus elephant, and the animal osteopath who is helping to manage her arthritis. Meanwhile, on Penguin Island, a killer disease strikes and hand-reared birds begin to die in the arms of the people who raised them. Can a cure be found before it is too late?
