Four Indigenous children, aged between 13 years and just one year old, survive alone for 40 days in the Colombian Amazon rainforest after a tragic plane crash in which they lose their mother. In one of the most hostile and inaccessible environments on the planet, they face hunger, torrential rains, predators, and absolute isolation. What guides them is not only instinct, but the strength of their family bond and the ancestral knowledge passed down by their Huitoto community. “Lost in the Jungle” is the powerful and rigorous account of a story that moved the entire world, restoring dignity and centrality to a tale of both childhood and cultural resistance. The documentary film weaves together archival footage, animations, and exclusive testimonies in a narrative reconstruction that gives voice to the direct protagonists – from the surviving children to Indigenous communities and rescuers – to restore human depth, perspective, and context to an event that became a national case. A moving reflection on the relationship between humans and nature, on the transmission of knowledge, and on childhood, told with respect and precision, recounting one of the most extraordinary stories of recent years.
