As the U.S. continues to build a wall between itself and Mexico, “Which Way Home” shows the personal side of immigration through the eyes of children who face harrowing dangers with enormous courage and resourcefulness as they endeavor to make it to the U.S.

The film follows several unaccompanied child migrants as they journey through Mexico en route to the U.S. on a freight train they call “The Beast.” Director Rebecca Cammisa (Sister Helen) tracks the stories of children like Olga and Freddy, nine-year-old Hondurans who are desperately trying to reach their families in Minnesota, and Jose, a ten-year-old El Salvadoran who has been abandoned by smugglers and ends up alone in a Mexican detention center, and focuses on Kevin, a canny, streetwise 14-year-old Honduran, whose mother hopes that he will reach New York City and send money back to his family. These are stories of hope and courage, disappointment and sorrow.

They are the ones you never hear about – the invisible ones.
