Ben Fogle and Kate Humble explore life behind the scenes at Longleat Estate and Safari Park. Using carcass-cam, a camera hidden in the skeleton of a carcass, we see how the lions really eat their dinner. The herd of near-extinct Pere David's deer has a new calf, the most precious baby in the park. But can she survive with a broken leg? And two-day old Gertie, Longleat's newest giraffe, finds her feet.
