While old Oliva tells a group of children about his life as a sailor and how he met Diana and her cat with sunglasses, a strange circus arrives in town.

The distressing fate of the Czech great Jan Amos Komenský, forced to leave his homeland after the White Mountain disaster. It depicts his encounters with various European personalities of the 17th century - the Queen of Sweden, artists and scientists. It emphasises the hero's nobility, but also his inner resilience, which allowed him to overcome many personal and professional tragedies. The parable of The Labyrinth of the World and the Paradise of the Heart becomes part of the story. However, Comenius's concept is sculpturally lifeless and, in particular, the religious dimension is "erased" from it. The simplistic biography therefore does not avoid schoolboyish dryness.
