A group of Falangist friends dreams of transforming Spain shortly before the Civil War while they are dedicated to spreading their ideas among the population. One of them, López, is about to die shot by firearm, but saves his life and joins the national side. At the end of the war, an old comrade encouraged him to participate in a secret operation to end the maquis of Asturias. Although he is already married and has children, he accepts the proposal and infiltrates the guerrillas.
