A beautiful teenage shepherdess named Adega sleeps one night with a mysterious pilgrim in a barn of impoverished and superstitious Galicia of the nineteenth century. The overwhelming fanaticism of the villagers motivates them to consider the outsider an envoy of Satan, reason why they deny him the lodging. The pilgrim, on the other hand, will react by cursing the people with plague and misery.
