A 1940 film directed by Manuel R. Ojeda,

Pastora de los Reyes is a beautiful Spanish that goes to Mexico with a contract to film a movie. The main actors will receive her at the airport, among them is Paul, a little-known mariachi that has been chosen to become a new idol. Automatically, both had bad relations and during filming many discussions happens. This arguments gives way to a deep love.

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.
