This film tells the unusually sensitive story of two women who try to cope with men, one a pragmatic gold digger type, not unsympathetic though, the other a dreamer who falls in love with a man in a magic moment ... or so she thinks.
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.

As it turns out, she's married to the smuggler Kerrylis, who forces her to take part in his business; that's why she tried to kill herself.

A romance between two temperamental singing stars. Highlights include a lengthy selection from Faust, with Gigli making a most impressive Mephistopheles. The plot takes a melodramatic turn towards the climax, with the lives of the characters mirrored in their on-stage behavior. Director Carmine Gallone was something of an expert in the field of filmed opera, as witness his Tosca, Rigoletto and Il Trovatore.
