 In the loud and contentious debate over immigration, there are voices that will never be heard—those of the more than 2,500 border crossers who have perished in the vast wasteland between Sonora, Mexico and Tucson, Arizona in the last 15 years. The Undocumented tells the story of these migrants who died while trying to cross an unforgiving desert in search of a better life, and follows them on their long journey home, shining a light on an often-forgotten but very human side of the ongoing national conversation about immigration reform. Directed by Marco Williams (Two Towns of Jasper, Banished), the film premieres April 29 on PBS' Independent Lens series.
