Ten years earlier Helga Andrée was convicted of the murder of her rival in love, the singer Elinor Gyldenborg. Today, however, Police Commissioner Husfeld has good reason to believe that Helga is innocent. But he lacks formal evidence. To get the wolf out of the den, he asks his friend, Volkmar Hollberg, a successful author of crime novels, to write a radio play based on the elements of the case.
