This dramatic story is situated in the town of Trnava of the 18th century. Painter Peter paints an altar-piece of the Martyrdom of St. Juliet and his model is a young girl. This is much disliked by the clergy who unjustly accuse the girl of witchcraft. She is saved from being burnt at a stake by the students of the Trnava University.
