An anti-war black comedy set during the Thirty Years' War. It follows ploughman Petr, recruiter Matěj and country girl Lenka who get caught up in both sides of the war and experience many adventures before they find happiness. The film combines live action with animation to suggest the artistic style of the engraver Matthäus Merian.
After an attack against the guard of the Third Reich, Nazi repression intensifies, and the Czechoslovakian resistance's organized sabotage in an aircraft factory leads to Gestapo shootings.
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.
