How did hunter-gatherers survive in Stone Age Britain? From flint-napping and bow-making to fire-lighting and cooking venison, Mears uses replicas of tools from that era to demonstrate - and celebrate - our lost bushcraft skills as he encourages us to view our land in a new light.

Mears sets up a jungle camp in the Amazon rainforest close to a native village, and sees how the Yekuana live in harmony with their environment. He encounters poison dart frogs and climbs into the forest canopy to gain a different perspective on the surroundings. He also offers an insight into the people who inhabit the dense tropical environment.

Mears encounters huge waterfalls, clouds of butterflies on a trek through the Amazon jungle in the shadow of flat-topped mountain formations called tepuis. He then journeys to the huge rock outcrops which inspired The Land That Time Forgot and The Lost World.

Mears makes a return visit to northern Tanzania to spend some more time with the Hadza, sharing a love of bows, tracking and the landscape with true hunter-gatherers whose way of life demonstrates a profound connection to the natural world.

Mears fulfils a childhood dream by experiencing a true safari, Maasai-style. He teams up with a Maasai warrior in Tanzania and embarks on a walking safari. As they travel through a valley inhabited by wild animals, he spots a variety of useful plants and ends the day sleeping under the stars.
