In 1945, three young brothers joined and eventually led Brazil's first government-sponsored expedition into its Amazonian rainforests. After more expeditions into unknown terrain, they became South America's most famous explorers, spending the rest of their lives with the resilient tribal communities they found there.

People of the Rainforest recounts the Villas Boas brothers' four thrilling and dangerous 'first contacts' with isolated indigenous people, and their lifelong mission to learn about their societies and, above all, help them adapt to modern Brazil without losing their cultural heritage, identity and pride.

Author and explorer John Hemming vividly traces the unique adventures of these extraordinary brothers, who used their fame to change attitudes to native peoples and to help protect the world's surviving tropical rainforests, under threat again today.
