At the far end of a street through the Jewish ghetto of a town in Asia there is the school of the Christian children. One boy always sings a Latin hymn to the Virgin Mary, Alma mater, when he returns from school through the Jewry. Satan persuades the Jews to kill the boy as he obviously does not respect their Holy Laws. A hired murderer slits the boy's throat and throws the body in a cesspool. His mother seeks him, when he has not returned from school. By the help of Jesus she comes near the pit she hears her son sing the Alma mater. The corpse is found, the Jews are fettered and killed, and the boy is taken to an abbey. There he tells the abbot that he has to sing until the grain put on his tongue by the Virgin is taken away. When the monks do so, the boy dies.
