Plot Summary:In this documentary short by director Luis Buñuel he travels to Las Hurdes, a remote region of Spain which was connected to the outside world only in 1922 with the completion of a road. The residents of the area - spread across several villages - lives in poverty and in isolation from the outside world. They survive mostly on a diet of potatoes and beans with meat available only a few days a week. In fact, they eat goat meat only when one of the animals dies. Inbreeding results in a disproportionately large number of people with mental disabilities. The title refers to the fact that the residents did not know how to make bread.
