The doctor at the "Abendrot" senior citizens' home, Dr. Rose Lang, was murdered. Ironically, in "Abendrot" Freddy Schenk also accommodated his grandmother Margot – against her will. Now he has a guilty conscience. In the home, there was obviously also tension between Dr. Lang and the nurse Tatjana Riegelsberger and the director of the home Erika Schubert. After the recent death of a senior citizen, the doctor had expressed clear criticism of the nursing shortage in the "afterglow". The home resident Mr. Kehl is convinced that his wife could have been saved if only help had been there in time. Another resident of the home, Konstantin Baumeister, died completely unexpectedly. Margot Schenk had just become friends with him of all people.
