Ben Fogle and Kate Humble are back at Longleat Safari Park for a very special episode, celebrating the life of Nico, the legendary western lowland silverback gorilla who recently died at an extraordinary 56 years old. Nico arrived at Longleat almost 30 years ago, and the programme hears from the keepers who looked after him for every day of his life at the park. We also reveal the story of his life before Gorilla Island as the team uncovers information charting a global shift in wildlife conservation. There is also a tribute to the powerful bonds formed between keepers and animals around the park. Tina tries to help a mammoth moose under attack from some pesky birds, while James gets stuck into the stinkiest poop on the park in a bid to stop his mischievous meerkats from escaping. Finally, the programme discovers how Nico's death affected thousands of visitors, all moved by their own encounters with him.
