"It's been 12 years since I've seen them", says Rosa, mother of two sons. They were teenagers when they travelled illegally to the US to become two of more than 12 million undocumented Mexican migrants north of the border. Although they send money home regularly, they are trapped apart from each other. "Because they are away from the family for many years... life is very hard" says Lupita, a Mexican woman whose brothers and husband are in the same position. Unable to attain a visa, they decided to form a female theatre troupe called CAFAMI. In an incredible twist, their cautionary play about the impact of Mexican migration to the US becomes their means of reuniting in America.
