Anna Jobst is the daughter of a rich, conservative farmer. Living on the bank of the Moldau, she wishes nothing more than follow the river to Prague, the "Golden City". After arriving, she quickly falls into a bad crowd.
In the mountains of the Ötztal, the wealthy Fender (Eduard Köck) and Wally (Heath Hatheyer), his only daughter and heir, manage a small farm. He wants to marry the rich, but boring, Vincent (Leopold Esterle). Wally escapes to a mountain hut, where she lives alone and withdrawn. Her love belongs to the hunter, Joseph (Sepp Rist). When she unwisely takes a young vulture from its nest and is attacked by the mother, Joseph comes to her aid and from that point on, she fondly calls him her "Geierwally". He also feels attracted to her, but Wally can't escape the feeling, that the young Afra is his mistress. Mad with jealousy, Wally announces that she'll marry the one who kills Josef. Vincent wants to earn her hand and is determined to kill the Geierwally. Just in time, though, the actual relationship between Joseph and Afra is clarified.
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.
