Feminist writer Karina Masur is at the Frankfurt Book Fair presenting her latest book, in which she advises women to kill their violent husbands and tells stories about women who did it. Young Christian Neumann, son of one of the victims mentioned in the book, publicly threatens her at the presentation and just shortly after Karina Masur is found killed at the stand. Neumann is arrested but his mother is sure he is innocent and asks Dr. Franck for help.
