Cary Fukunanga’s searing directorial debut is the tender story of siblings Sayra and El Casper traveling by train through Mexico to the United States. While Sayra, who is with her family, seeks a better life in the north, El Casper is fleeing retribution from the gang Mara Salvatrucha (MS-13). An intimate portrait of youth, Sin Nombre also alludes to the political, international, and historical forces that render the journey between Central America and United States brutal, corrupt, and often insurmountable. 2009, 35mm, 96 minutes.
