"Sad Happiness: Cinthya's Transborder Journey' is an ethnographic film that explores the differential rights that U.S. citizen children and their undocumented parents have through the story of one extended Zapotec family. This story illuminates the desires and struggles of the millions of families divided between the U.S. and Mexico -and other countries- where children are mobile citizens and parents cannot leave. This film is in English, Spanish, and Zapotec with English subtitles.
