Song Without A Name is based on real events where poor Native Amerindian women had their newborn children illegally adopted without their knowledge or consent. Even when the struggle to bring those to justice is finally over, the attitude prevails that these kids are probably better off with the rich whites that have adopted them overseas than with their poor indigenous mothers, so no real effort is put into reuniting them.
For the main character, this just destroys her and her husband. Unable to provide or protect his family, he falls into despair and is led astray by a bad lot. She is left in this permanent state of unresolved mourning.
A sorrowful tale.
