Season Five of TRAFFICKED WITH MARIANA VAN ZELLER Premieres July 19 at 9/8c on National Geographic and Streams Next Day on Hulu

(Washington, D.C. - July 3, 2025) National Geographic announced today that nine-time Emmy Award-winning investigative series TRAFFICKED WITH MARIANA VAN ZELLER will return for its highly anticipated new season on Saturday, July 19, at 9/8c. Known for her fearless reporting and unparalleled contacts with the world's most dangerous black markets, Emmy, Peabody and duPont Award-winning journalist Mariana van Zeller pulls back the curtain on global criminal enterprises - from cartels and scammers to militant extremists and underground drug labs.

In the wake of four News and Documentary Emmys wins last week (adding to the five from the year before) and scoring a record 29 nominations this year alone, the new season of TRAFFICKED continues van Zeller's immersive, on-the-ground reporting in some of the world's most secretive underground markets. The new season kicks off with a groundbreaking look into the operations of Mexican cartels inside the United States. The results are shocking. From small-town drug cells, van Zeller explores how these criminal groups move drugs, launder billions, and even infiltrate law enforcement. It's a growing influence that's fueling violence and addiction across the country.

Armed with National Geographic's trademark inside access, each episode follows van Zeller as she connects with traffickers, militias, scammers, smugglers, and law enforcement across the globe to investigate the inner workings of a multi-trillion-dollar shadow economy. From high-level criminals to frontline victims and government insiders, van Zeller's reporting offers a 360-degree view of the forces shaping our increasingly interconnected, and blurred, legal and illegal economies. Premiering weekly, the series exposes the human cost of these hidden worlds and why they matter more than ever.

"This season mirrors the times we're living in," says van Zeller. "The issues we investigate - from the growing reach of cartels in the United States to the expanding world of scams - don't happen in isolation. These are societal stories, rooted in desperation, exploitation, and the global forces shaping our future. Hidden stories that ultimately affect us all."
