Alambrista! (1977)

After his daughter's birth, Roberto leaves his town in Michoacan to make money in the United States. He's "an illegal," crossing into California and taking work wherever he can: picking strawberries, grapes, lettuce, and cucumbers. He hitchhikes, rides freight trains, and depends on the kindness of strangers. Near Stockton, things look up when a sympathetic waitress gives him a place to live, and he gets a better job at a crop-dusting company. But immigration raids are a constant possibility that can end stability. Can Roberto hold onto his equilibrium in this foreign land where hard work is not enough?
