Kate Humble and Ben Fogle join the keepers and animals for another sun-soaked episode at Longleat Safari Park. This episode focuses on some of the planet's most endangered species and joins the keepers striving to save them. The carnivore team spend a gruelling 24 hours trying desperately to keep alive a precious cheetah cub born just 36 hours before. What will the keepers do as they face a life-and-death situation when they reunite this cub with mum Wilma? Jean Johansson has her hands full when she helps with the weigh-in of the cutest newborn baby meerkats, and using a macro lens she gets closer than ever before to a very special breed of seahorse. Meanwhile, can the park stop the desertas wolf spider from being wiped out forever?
