A classical who-dunnit-detective-story in an unusual setting: In the retirement-home for aging stage-artists "Ewige Rampe", an overly engaged doctor discovers what seems to be a murder by poison. The victim is the only inhabitant of the home who was not on stage, but a reporter of a gossip magazine.

Florestan Mississippi, a public prosecutor by profession, visits a lady named Anastasia and, while drinking coffee with her, convicts her of poisoning her husband. At the same time, he asks for her hand in marriage, as he too has killed his wife with poison; the marriage is to be the "atonement" of the two poisoners. The four allegorical personifications in this comedy are, in addition to the loveless, absolute justice in the form of the prosecutor Mississippi, perfect equality, represented by the world revolutionary Saint-Claude, Christian love, embodied in the down-and-out, alcoholic tropical doctor Count Uebelohe-Zabernsee, and finally the "Frau Welt" of the old mystery play – Anastasia, who falls for everyone and betrays everyone, loves nothing but the moment, and dies with an invoked untruth on her lips.

In the middle of the 19th century, almost one in three women who gave birth died of puerperal fever. The Hungarian doctor Ignaz Philipp Semmelweis also observed these terrible occurrences in his clinic in Vienna. He came to the conclusion that it was primarily the unhygienic conditions in the clinic itself that led to this disease, as his colleagues were constantly shuttling back and forth between the anatomy department and the delivery room. He tries to convince the doctors of the absolute necessity of thorough disinfection by washing their hands with chlorinated lime. He meets with fierce resistance from his colleagues until he himself sets up an exemplary clinic in Budapest.
