For the last twelve years, Marisela and Ely, along with the volunteer group The Águilas del Desierto have roamed the US-Mexico desert. Their goal: to seek, find and return to their families the bodies of migrants who died while crossing on foot. This all-consuming calling takes a crushing toll on them, but how could they stop? Spare My Bones, Coyote! follows their work, dedication, and difficult lives they have chosen to live.
