The film is a sort of a love story with a tragic end. Produced by Diego Luna and Gael Garcia Bernal. Written and directed by Cary Joji Fukunaga.
“Sin Nombre” means “without name” in Spanish, which I guess refers to the fact that the story could take place anywhere and to people that in the large spectrum of things are nameless faces falling into this particular social cultural trap of either joining a gang or trying to escape your conditions and trying a new life crossing the border of the United States illegally.
The story follows two parallel journeys that inevitably meet, brought together after a fatal encounter. The first, by far liveliest voyage begins in the chaos of Tapachula in Chiapas, Mexico, where Casper (Edgar Flores), a teenage member of the vicious street gang Mara Salvatrucha, is making a fast run toward an early grave. Casper meets his destiny when his story collides with that of Sayra (Paulina Gaitan), a solemn-eyed, extremely naive Honduran teenager who is riding the rails to Texas with her father and uncle. The teenagers meet cute, gangsta style, when another Salvatrucha member attacks her during a heist on the train and is assaulted in turn. As the journey continues they begin to fall for each other avoiding a fellow gang member who has been sent to kill him along the way until destiny reaches Casper and he finds death when he is about to cross the river to the United States.
