Chelelo then recounts the story of two revolutionary friends, Sub-lieutenant Valente Quintero and Major Atanasio Pizarro, who fought in a battle in one of Perales' residential streets.

Leonor then tells her mother that she is returning a favor that could have been made to her father, who died bleeding in the midst of a forest.

Atanasio falls in love with the elegant and sophisticated Leonor and admires the conservative and sharp-tongued matron Elvira.

[1] La yegua colorada, the first film directed by Mario Hernández, had been shot in January 1972 but was released later than Valente Quintero.

The film premiered in Mexico City, on April 12, 1973, exclusively in the theaters Mariscala, Carrusel, De la Villa, and Marina for six weeks.
