Traversing more than 1,450 miles upcountry, Mexican freight trains routinely are boarded by migrants hoping to reach America. Among the thousands who ride the trains, many are children traveling alone. They come from all over Mexico and Central America, risking everything for the chance of a better life. Academy Award nominee "Which Way Home" follows some of these unaccompanied children as they make the long and treacherous voyage to the U.S. border. Some, like Olga and Freddy, venture out in search of distant relatives. Others, like Kevin, hope to find work to support their families at home. Often traveling for months or even years at a time, these courageous and determined children each have stories of hope and resilience, disappointment and sorrow. Chronicling the harrowing journey of thousands of migrant children, "Which Way Home" illuminates a powerfully human side of immigration.
