This entertaining comedy is set in 1938 during the Spanish Civil War when a group of Republican soldiers sneak into a village in enemy territory to steal a bull with plans of butchering it to feed themselves. Fate and the bull itself, however, have other plans. One of the surreptitious bull-snatchers knows the village well -- he grew up there, but that advantage alone cannot guarantee their success, as it turns out. The group of five would-be thieves dress themselves in uniforms of the Nationalist troops in an attempt to dissimulate their true identity. But instead of a neat getaway with a bull in tow, they are caught up in the "correo" or running of the bull, they get involved in a religious procession, and in the end, watch as the bull breaks out of a flimsy ring in a bullfight and heads for the hills. Still hungry, the group of men now have to worry about getting back to their own battalion before they are found out.
