Synopsis: "The title refers to the wall used by firing squads to execute prisoners. Pablo Ibbieta, along with two others in his cell, is sentenced to death. He is offered a way out if he reveals the location of his comrade, Ramón Gris. Pablo begins thinking to himself and finds that he no longer cares about his cause or his life. Pablo continues to refuse to cooperate until just before his scheduled execution, when, seeing no harm in it, he gives the authorities what he believes to be false information on Ramón Gris' whereabouts. Ironically, it turns out that Ramón Gris has moved from his previous hiding place to the very spot where Pablo tells the authorities he may be found. Thus Ramón Gris is shot and Pablo's life is, at least temporarily, spared from death." (Wikipedia)
