Film Club: The River and The Wall

Conservation filmmaker Ben Masters realizes the urgency of documenting the last remaining wilderness in Texas as the threat of new border wall construction looms ahead. Masters recruits NatGeo Explorer Filipe DeAndrade, ornithologist Heather Mackey, river guide Austin Alvarado, and conservationist Jay Kleberg to join him on the two-and-a-half-month journey down 1,200 miles of the U.S.-Mexico border.

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.
