New Nat Geo documentary details young siblings' incredible story of survival in the jungle

National Geographic has released the trailer for its gripping new documentary, "Lost in the Jungle."

The story is about four Indigenous siblings, aged 13, 9, 5 and 11 months, who were stranded in the Colombian rainforest after the small plane they were on crashed on May 1, 2023. The crash killed their mother and the pilot and the children spent 40 days trying to survive alone in the dense jungle.

For the first time, the children detail their incredible story of survival as the Colombian military teamed up with Indigenous trackers to search for them.

"Lost in the Jungle" is directed and produced by Colombian filmmaker Juan Camilo Cruz, along with Chai Vasarhelyi and Jimmy Chin, who are best known for "Free Solo" and "The Rescue."

"Our work has always been about the raw power of the human spirit-its ability to rise, unite and overcome. LOST IN THE JUNGLE is that spirit in its purest form," said Vasarhelyi in a statement. "Teaming up with Juan Camilo Cruz is a true privilege. His powerful vision and deep connection to Colombia bring authenticity and heart that elevate this film at every level."

"This story intrigued us from the very first time we heard about it," added Chin. Working with Juan and the amazing team in Colombia allowed us to really showcase incredible details about the rescue and survival like never before. We hope audiences leave as inspired as we were by Lesly and the powerful partnership among the rescue teams."

"As a Colombian filmmaker, I'm deeply proud to tell a story that honors Indigenous people and the wisdom rooted in their land," said Camilo Cruz. "LOST IN THE JUNGLE is a tribute to the extraordinary courage of four children-true heroes-and a reminder of the Colombian jungle's true value, far beyond its resources. For me, their journey is a powerful example of what Colombia can be: When we set aside our differences and come together, we can achieve the impossible. That's a message the world urgently needs to hear."

"Lost in the Jungle" will make its world premiere at the Telluride Film Festival. It'll air on National Geographic September 12 and stream the next day on Disney+.
