Growing up, Ben Masters worked on West Texas ranches along the border where he developed a love for the outdoors and wildlife. The experience eventually led him to study wildlife biology and to become a filmmaker.

But his interests shifted after the election of President Donald Trump and Trump’s insistence that the U.S. erect a wall along the entire U.S.-Mexico border.

Masters’ new documentary examining the diverse wildlife and landscape of the Rio Grande along the U.S.-Mexico border debuted last week at select theaters nationwide and on iTunes. “The River and The Wall” follows five people, including Masters, who take a 60-day journey along the Rio Grande from El Paso to Brownsville, Texas.

They travel by foot, mountain bike, canoe and horseback to document the natural physical barriers that already exist along the 1,200-mile Texas-Mexico border. They also film wildlife and talk to border residents who see the region as one and who oppose plans to build a wall in rural, isolated areas.
