Puro siccome un angelo papà mi fece monaco... di Monza

The story

A noble family assigns their younger son to the convent. The youngster has an affair with a novice, who becomes pregnant. The brothers, exasperated by his arrogance, denounce him to the Inquisition. As a punishment, the boy is walled up alive and released after fifty years. Due to a mysterious miracle, however, he remained as he is, just like the novice he impaled.
