President Donald Trump’s “zero tolerance” immigration policy drew sharp rebukes after it was announced in April 2018 — especially after children who had been separated from their parents started being placed in a tent city in Tornillo. Trump signed an executive order June 20 that would keep immigrant families together, but it’s unclear how — or if — families that have already been separated will be reunited. With support from the Pulitzer Center on Crisis Reporting, The Texas Tribune has been reporting on the issue from the Texas-Mexico border, Washington, D.C., and Austin.

Carlos and his 6-year-old daughter, Heyli, traveled nearly 1,700 miles together from Honduras to reach the U.S. border — and what they hoped would be the start of a new, better life — only to be separated by more than 1,200 miles shortly after they surrendered to Border Patrol agents and requested asylum. Along the way, they became small players in a shadowy, multibillion-dollar global enterprise: the smuggling of human beings for profit.

In this documentary, The Texas Tribune and TIME traced their journey and investigated the booming smuggling industry that has thrived as the U.S. government seeks to close America’s southern border and as record numbers of migrant families make the long trek north.
