Very few of us would embark on a journey to the Congo to find a lost sibling, as does Sara, a naive Madrid lawyer. She is forced to become aware of a brutal reality that most of us ignore yet that supports our technology: African mafia bosses routinely murder entire villages while kidnapping children to serve as soldiers to control mines that produce minerals needed for high-tech products. Menaced by literal and figurative snakes (both foreign and native), Sara also experiences incredible acts of kindness and courage by Africans, a stark contrast with inhumanity of the few. In the end, the movie leaves us wondering whether it is noble or futile to try to intervene.
