Kate Humble and Ben Fogle have raced back to Longleat safari park in time for a spectacular summer series, and it promises to be one of the busiest seasons ever. Every corner of the park is home to a wildly different exotic species, each with its own needs. With unique access, this series exclusively reveals the extraordinary lengths the devoted keepers are willing to go to for the creatures in their care to lead long and happy lives. Kate and Ben are on hand to celebrate some of the extraordinary "firsts" that the park has become famous for, including the arrival of a new species, the African painted dog. And can Hamza Yassin uncover a lorikeet love match in the aviary?
