The creative fingerprints of executive producer Stephen Spielberg are evident throughout this documentary that functions as a mystery, a dramatic exposé of a little-known Guatemalan massacre, and a piece of humanitarian detective work that reunites the remainder of a family. On the night of December 6, 1982, the special forces of a Reagan-backed Guatemalan military regime descended on the tiny rural village of Dos Erres for a murderous spree that left every man, woman, and child dead. Years later, as the site is excavated and bodies exhumed, a perpetrator reluctantly confesses that two small boys were kidnapped and taken home by soldiers. One is located, and a 15-year search for the other, Oscar, ensues, unraveling a powerful story that encompasses history, politics and culture, and speaks to human endurance. In English and Spanish with English subtitles. DCP digital
