As the hopeful trio heads north, the silent Tzotzil Indian boy, Chauk, joins in the perilous journey to illegally cross the Mexican border into the United States of America. Facing arrest; violence; marauding gangs; La Migra, and even death, the foursome have to hop freight trains and keep a low profile to reach the promised land; however, what future awaits once they make it into the US?
