There are several parallel stories told in the documentary “Finding Oscar.” The main one lays out, with traditional means, the horrific circumstances of a 1982 atrocity perpetrated by Guatemalan army commandos against the residents of a small Guatemalan village. Taking its name from the location of the raid, the so-called Dos Erres massacre left 250 civilians dead — many of them unceremoniously dumped down a well, with some thrown in while still alive — by a squad of elite military operatives, known as Kaibiles.

In the small Guatemalan village of Dos Erres in 1982, 250 people were killed by government soldiers. The documentary, "Finding Oscar," traces the story of one of the few survivors who didn't even know his own history until recently. It also explores the U.S. government's role in the Guatemalan civil war, which lasted from 1960 to 1996.
