During the Spanish Civil War on the Aragón frontline the speakers of the Nationalist troops announce a festival in a nearby village which includes a bull run and religious procession. A group of Republican soldiers infiltrate the Nationalist side to steal the animal for two reasons; to ruin the holiday for the Nationalists and because their food stores are low.
Mariano (Guillermo Montesinos), a Republican soldier coming from a village across the frontline, where his girlfriend Guadalupe remained.
Limeño (Santiago Ramos), a Republican soldier who was a bullfighter before the war. Chosen to kill the heifer, he is actually afraid of bulls.
Lieutenant Broseta (José Sacristán), a Republican officer who was a hairdresser before the war. He longs for his profession and threatens to punish failure with a complete head shave.
Priest (Carles Velat), a Republican soldier who almost became a Catholic priest. He still remembers many mannerisms.
The marquis (Adolfo Marsillach) is the local aristocrat. He tries to convince the commander to push the front so that all his enormous estate (currently divided by the frontline), falls in the Nationalist side. His "inherited" gout forbids him to walk.
Location
