Kate Humble and Ben Fogle return to Longleat Safari Park for another spectacular summer series following the fascinating stories of the exotic animals and the keepers who look after them.

Earlier in the series, the wolf pack was rocked by the death of pregnant mother Aliska. She died whilst she was in labour along with her pups. Now, another problem is looming, and this time the focus is on her partner, Jango. He has been showing signs of a urinary infection, so the keepers have brought him into the wolf house. It's soon obvious that the problem is bladder stones, but if the vets cannot flush them through, Jango's only other option is a risky operation. The keepers are nervous because this was exactly the condition that caused the death of much-loved timber wolf Dave.

At the park, keepers often need to come to the aid of an animal in need, so sometimes it's nice to stop and admire the beauty and majesty of the creatures, which is exactly what wildlife cameraman Hamza Yassin has an opportunity to do today with the cheetahs. With his zoom lens, Hamza is able to get close enough to see their incredible claws, which unlike most cats' cannot retract, and investigate their incredible markings, which are not just on their fur but in fact go right through to their skin.

Also today, Thorn the giraffe is being trained so that he can receive a giant pedicure, zoologist Megan McCubbin serves up some ice lollies to the donkeys to try to keep them cool, and Ben creates a scent trail for one of his favourite animals, the tapir.

Lions, tigers and wolves are all fiercely territorial and will fight off newcomers without hesitation, but when it comes to defending their patch, few creatures are more fearsome than rabbits. Keeper Gemma attempts to introduce a pair of new rabbits into the group already at the park. She begins by creating a wall down the middle of the enclosure, so all the rabbits can sense each other, but even this is not without risk. Serena, one of the largest and oldest rabbits in the group, could become overwhelmed by the situation, and there is a real risk of her suffering a heart attack.

Meanwhile, Kate helps Caleb as he attempts to fire up the wild instincts of the famous lions, and Ben discovers how those same animals helped Lord Bath save Longleat House from ruin over 50 years ago.

Wildlife cameraman Hamza Yassin trains his long lens on his favourite animals at the park, the gorillas. The keepers have noticed some changes in the hierarchy between the boys, but what clues can Hamza find to back up the keepers' theory? Megan McCubbin helps start a training programme for the pygmy goats and discovers how the keepers are attempting to reduce the food miles of the park's Australian koalas to zero.
