Ben Fogle and Kate Humble are back for another glorious summer series, following the incredible lives of the exotic animals at Longleat Safari Park and the keepers who care for their every need.

There was shock last year, when a surprise family turned up at the park and established a home. Beavers started building a lodge on Half-Mile Lake, remarkably sharing it with two hippos, half a dozen sea lions and a couple of big boats. What’s even more surprising is that the last time beavers roamed this area was before Longleat House was completed in 1580. We reveal if they are still in residence. The keepers have been filming throughout the year, using camera traps, and the signs suggest they have settled. When they scroll through the lakeside CCTV, the keepers make an extraordinary and completely unexpected discovery. Has the beaver family grown?

Wildlife cameraman Hamza spends months on end filming exotic animals in far-flung places, but in today’s episode he faces perhaps his biggest challenge yet. Can he film the famously illusive beavers in real life?

Also, tensions between a female tiger and her daughter are approaching boiling point. Normally solitary animals in the wild, the tigers are showing signs of territorial battles in the park’s drive-through. Will the keepers be able to stop these arguments escalating into a potentially lethal conflict?

Elsewhere, Ben is in the East Africa Reserve to encourage the ostriches to run as fast as they might in the wild. Show less
