As the national debate over immigration policy simmers to a boil, its practical consequences are felt every day in Brooks County, Texas. Located 70 miles north of the border with Mexico, it is the site of an estimated 3000 deaths since 2008, as migrants try to circumvent the state's busiest interior immigration checkpoint and find themselves lost in the vast private ranch lands that surround it. ? Missing in Brooks County follows the journey of two families who have come to Brooks County to look for their loved ones who went missing. As they search for answers, they encounter a haunted land where death is a part of everyday life. A gripping documentary mystery, it is also a deeply humane portrait of the law enforcement agents, human rights workers, and activists who come face to face with the life and death consequences of a broken system.
