A penetrating humanistic portrait of a contemporary exodus, The Infinite Border profiles a handful of the hundreds of thousands of Central American migrants who enter Mexico clandestinely each year en route to the promised land of the United States. Some are incarcerated and some are sent back, only to return undeterred. Some bear the brutal evidence of the dangers of riding the rails northward in the form of severed limbs. Meanwhile, construction of the fence almost 10 meters high and over a 1000 kilometers long that will separate the United States from Mexico continues unabated. An evocative story of determination and hope through the lives and dreams of those who travel in search of a better life.
