The Baron Munchausen (Milos Kopecky) is an over-the-top storyteller whose fantastic adventures take him everywhere from dusty Turkish battlefields to the deepest recesses of a whale's belly. When the Baron, who is enjoying a relaxing stay on the moon, is joined by gregarious space traveler Cyrano de Bergerac, the duo set off on a round-the-universe journey that will introduce them to the beautiful Princess Bianca (Jana Brejchová) and the formidable Tonik (Rudolf Jelinek).
