Five friends travel from El Paso to the Gulf of Mexico along the Rio Grande via bicycle, horseback, and canoe, exploring the relationship between the river and the proposed wall along America's border with Mexico.

The River and the Wall follows five friends on an immersive adventure through the unknown wilds of the Texas borderlands as they travel 1200 miles from El Paso to the Gulf of Mexico on horses, mountain bikes, and canoes. They set out to document the borderlands and explore the potential impacts of a wall on the natural environment, but as the wilderness gives way to the more populated and heavily trafficked Lower Rio Grande Valley, they come face-to-face with the human side of the immigration debate and enter uncharted emotional waters.
