"The film tells the story of women who live in Tijuana and what their lives are like working in the nearby factory. Carmen Duran, a single mother of three, was denied a severance payment that is legally required. The film also focuses on another protagonist who discusses the environmental damage the factories have done to her town and how things have changed since she was a child, such as the river no longer being safe to play in.

The women had to endure poor working conditions that impacted themselves and their neighborhoods. The poor conditions include smelling like burned plastic when they leave the factories, being harassed by employers, not being allowed to drink or use the bathroom (leading to kidney problems), not being given severance when the company decided to leave, and chemicals polluting their neighborhoods (leading to health complications such as difficulty breathing, skin rashes, and hives), among other issues." via Wikipedia
