In 1936, Maria (Ariadna Gil), a young nun is recruited by Pilar (Ana Belén), a militant feminist, into an anarchist militia following the onset of the Spanish Civil War.

[3] Militia women Pilar (Ana Belén) and Floren (Victoria Abril) are joined by former prostitute Charo (Loles León) and former nun Maria (Ariadna Gil), who had hidden in a brothel to escape revolutionary violence against clergy.

The film opens with scenes of working class militants demolishing and burning religious icons, as they shout "down with Capitalism!"

While fully immersed in the overall enthusiasm of revolutionary Spain, Pilar and friends find themselves fighting against deep gender inequality which complicates their efforts in the war against Francisco Franco's Nationalist/Fascist/Catholic forces.

Time Out stated that the movie "deserves praise for its feminist perspective on the course of the 1936-7 revolution, when women's liberation was a logical, if hardly well-recognised, constituent of the libertarian ideals that the Spanish working class rose up to assert.
