خلاصه داستان : کارگران مکزیکی در یک معدن روی، اعتصاب عمومی اعلام می‌کنند. تنها از طریق همبستگی کارگران و مهم‌تر از آن، اراده‌ی شکست‌ناپذیر همسران، مادران و دخترانشان است که سرانجام پیروز می‌شوند.

At New Mexico's Empire Zinc mine, Mexican-American workers protest the unsafe work conditions and unequal wages compared to their Anglo counterparts. Ramon Quintero helps organize the strike, but he is shown to be a hypocrite by treating his pregnant wife, Esperanza, with a similar unfairness. When an injunction stops the men from protesting, however, the gender roles are reversed, and women find themselves on the picket lines while the men stay at home.
