The newest PBS documentary film "East of Salinas," which is about the status of the farmworkers' children in a small part of California in Salinas Valley, is gaining much attention as the series by Independent Lens, which airs today, tackles the issue of the education and lifestyle of migrant labor workers in the U.S.

The documentary is scheduled to premiere on Dec. 28 on most PBS stations. The film will focus on one family in Salinas Valley, a place in California known for its vast fields of vegetable crops. The fields are, of course, plowed by farmworkers, whose lives and families will be featured in the film.

While the place is rich in harvest for the workers to share, the story reveals that these farmworkers and their families do not get to experience the fruits of their labor as they are still struggling in putting food on the table and education.

NBC News reports that the story is about Oscar Ramos, a third-grade teacher in Sherwood Elementary School, who is also the mentor of a farmworker's child, Jose Anzaldo. According to the award-winning filmmaker Laura Pacheco, she caught the story of Ramos back when she read a 2011 New York Times article.

Half of the students of Ramos, according to Pacheco, is made up of farmworkers' children. These children are undocumented and, therefore, having a hard time receiving proper education.

"We decided to follow one to get an intimate look of what a migrant family is like in America," Pacheco said as quoted by the publication.

When Pacheco, along with co-director Jackie Mow, decided to kick off their project, they followed Anzaldo around since he was in third grade. Now, Anzaldo is in seventh grade, just in time for the premiere of the long-term project.

"In the beginning, he's a little naive about his situation, and at the end he becomes more aware," Pacheco said of Anzaldo. "It's really hard to see someone's potential, and then leave and not know if he's going to have food the next day -- Oscar (his teacher) still goes to see them and takes the boys to the movies."

Furthermore, PRI revealed that Ramos was not just a teacher for Anzaldo but also a mentor and somehow a second-parent since the child's parents leave him in school to have work in the fields for the whole day. It is a tough role to fill since Ramos also guides the students not to be involved in other external factors such as crime and pressure from gangs in their neighborhood.

The documentary "East of Salinas" airs Dec. 28 at 10 p.m. ET.
