Several generations of the Germinger police family live together at Schwarzach 23, meaning that police work continues even at the lunch table. Successful Detective Chief Inspector Franz Germinger Jr. (Maximilian Brückner) takes charge of the investigation into the murder of a scrap dealer. He is assisted by his colleague Karl (Jockel Tschiersch) and his sister Anna (Marlene Morreis). Anna has already been forcibly transferred and demoted twice - though that does not stop her from overstepping her bounds once again.
