The Hidden River

A team of explorers sets out to uncover the many secrets hidden along the estimated 1,000km length of the Essequibo, one of the largest rivers in South America. The river rises in Guyana's Acari Mountains, near the Brazilian border, and flows through impenetrable jungles and treacherous swamps before finally reaching the Atlantic Ocean. The team crosses unspoiled landscapes, discovers rare species and contacts indigenous people.
