(CNN) A new Bernie Sanders campaign ad is highlighting the plight of migrant workers in Florida in an appeal to the Sunshine State's Latino population days ahead of the March 15 primary.

The ad, titled "Tenemos Familias" ("We Have Families") isn't a typical campaign spot -- it's a five-minute mini-documentary narrated almost entirely in Spanish with English subtitles, spotlighting an immigrant mother named Udelia Chautla who moved her family from Mexico to Immokalee, Florida, where she works as a labor worker picking tomatoes.

In the ad , she talks about her experiences working in the fields with low wages and poor working conditions, which led her to join protests with the Fair Food campaign in 2010. The protesters were asking corporations to pay one cent per pound more for tomatoes to provide labor workers with better pay and benefits.

"There were cases of bosses abusing workers," Chautla says in Spanish. "They would not provide workers with water or restrooms. The bosses would get angry because some of the men wouldn't want to keep working and start hitting them ... It affected my children because I didn't have enough to buy food."

Chautla continues by talking about Sanders' efforts as a senator to help the workers. He traveled to Immokalee and met with labor workers in 2008, and then invited the Coalition of Immokalee Workers to Washington to testify during a Senate committee hearing regarding abusive labor practices. As a result, the ad says, their working conditions improved and they received a wage increase.
