Kate Humble and Ben Fogle return to Longleat Safari Park for a spectacular, sun-drenched summer series, following the remarkable lives of the exotic animals and the keepers committed to help them.

In this episode, a cowardly lion is in danger of being attacked by her fellow lioness. Beryl's solitary behaviour is putting her in peril, as an unconfident member of the pride can be rejected. To ensure her standing in the group, the keepers have come up with a plan to elevate Beryl's status amongst the lionesses and build up her confidence.

It's been three years since Europe's only southern koala breeding programme started, and Animal Park has followed every step of the phenomenal journey. There has been some incredible news, and it's all been caught on camera. Violet started putting on weight last year, and after a few months there were signs that there was life inside her pouch. The keepers nervously wait for signs that their hopes of a precious joey could come true.

Elsewhere, Ben helps geriatric pygmy goat Jake have his first bath. Kate meets the park's eastern black and white colobus monkeys and finds out why they appear to have a ‘cape,' and how they move around their own island.

Wildlife photographer Hamza Yassin is back for another series, using his specialised kit to help the keepers solve some of the trickier problems across the park. Today, there's a mystery to solve: can he sex the three baby Pere David deer?

This summer we have a new member of the team, zoologist Megan McCubbin. She's finding out how the keepers in the park keep their animals entertained and in great condition - and as a former animal keeper herself, Megan needs no encouragement to get stuck in. Today, she's helping the keepers encourage the Amur tigers to swim in their pond. They are surprisingly powerful swimmers with partially webbed paws.

Kate Humble and Ben Fogle return to Longleat Safari Park for another glorious summer series, following the incredible stories of the exotic animals and the keepers who look after them. There have been many successful newborns at the park over the years, but today we find out why breeding programmes are not always easy.

There's a race to stop one of the park's most important breeding programmes from falling apart. Last year, the park joined a red squirrel breeding programme, and they have already had babies. However, those babies are already nearly adults, they're squabbling, and they can't live together. So they need to be separated. But you can't just catch a squirrel as it's too stressful for them, so the keepers have to make a plan. With the animals' safety at stake, this is one move that can't happen soon enough, but can the keepers do it without causing serious stress to the squirrels?

Also, could it be 'maybe baby' for one of the park's most endangered species? Kate meets a new female red panda, who has been paired to breed with a male. Kate sees that there are exciting signs that she could indeed be pregnant, and she helps the keepers weigh her. Meanwhile, wildlife photographer Hamza Yassin tries to confirm whether one of the other female pandas is building a nest high up in the enclosure's tree? If so, it might be a sign that she could also be pregnant.

Elsewhere, Ben is serving dinner to a pair of cold-blooded killers, the Cuban crocodiles, and he has brought ‘Croc Cam' to capture every bite. Zoologist Megan McCubbin continues to find out how the keepers in the park keep their animals entertained and in great condition. Today, she uses her skills as a former animal keeper to muck out the park's collection of Rothschild's giraffes and help identify whether a camel has a tooth problem.
