A Latin teacher named Valentín Mosquera (José María Seoane) wanders through the night, stalking the  streets of Madrid and trying to come to terms with the fact that his son Mario will be executed at dawn.  This is an indictment of the death penalty as well as the debut of director Amando de Ossorio, this was filmed in secret and never released to theaters. This was seven years before Luis García Berlanga’s El Verdugo caused a major controversy at the Venice Mostra Film Festival.

Based on a play by Horacio Ruiz de la Fuente, this first played at the Belgian Experimental Film Festival and Ossorio said of it, “It was banned, they didn’t give us permission to shoot it. But we stubbornly did it.” It was made because he convinced law student Francisco Javier Pérez de Rada y Díaz Rubín, son of the Marquises of Zabalegui, to finance the filming.

It’s unlike anything else in his filmography, as after this he soon moved from human terror to the supernatural.
