When Mexican drug cartels fight for control along the border, Juarez becomes the murder capital of the world. In El Paso, Texas it's drug business as usual: a grifter sets out to buy her freedom, a car salesman runs drugs to make his fortune, a gang leader battles to rise among the ranks of the cartel, and a detective and his wife are ripped apart by a family secret. Everyone's fate lies in the hands of an old woman. Will she let the past die with her, or take revenge the only way she knows how?
