The young Schiller, whose heart and soul are writing and poetry, is forced into the military academy (the pride and joy of the Duke of Württemberg). Schiller is disgusted by the everyday routine of the military, always back and forth between breeding and drills. Conversation, conflict or even critique are discouraged – the oppression insufferable for the young rebel. Disgusted by the brutality, he writes his drama "The Bandit", which he would later publish anonymously. But following a frank conversation with the Duke, Schiller is dishonored and must leave the land.
Country Dr. Robert Koch is desperate: a tuberculosis epidemic is decimating the children in his district and no one is able to do anything about it. Every fourth child is already sick and the parents must helplessly watch as their young ones die. Now Koch is undertaking to find the cause of the tuberculosis --- something he has already been working on for years --- which has been causing this plague of illness. His work is made more difficult by envy; for example, that of his teacher, who was wounded defending his honor. But his greatest obstacle is the famous Berliner scientist and Reichstag deputy, Privy Councilor Rudolf Virchow: He is extraordinarily skeptical of Koch's theory, that the cause for tuberculosis is a bacteria.
The delightful Johann Strauss comic opera Die Fledermaus was mercilessly lampooned in this truly bizarre production. For starters, a framing device has been added: After appearing in 300 consecutive appearances of Fledermaus (which translates as The Bat) the lead tenor (Georg Alexander) imagines that he's seeing bats everywhere. Driven a bit over the edge by all this, he falls asleep and has a nightmare about the opera, with a group of non-singers cast in the leading roles. The original libretto about romantic assignations, political imprisonments and mistaken identity is burlesqued to the hilt: at one point, the hero finds out that his prison cell is surrounded by rubber tubes!
