Mothers sometimes leave home to provide a better life for their families, seeking work in the U.S. And sometimes their children travel alone after them, trying to find them. Which Way Home, by film-maker Rebecca Cammisa, is a wrenching documentary about children traveling from Central America, seeking their mothers in the United States. Heartbreaking.
