When a father, Luis Salazar, travels illegally from Mexico into the United States to search for his missing son, he discovers that modern servitude is thriving in the farmlands and agricultural communities. Promised a job and a place to live, these laborers find themselves forced to live in abject poverty. Required to pay for their own food and other essentials, what little money they make is paid back to their employers, and because they will forever be in debt, they can never leave.
