In this thriller series the whole family is full of cops. Both Carla and Rudi Krause are police commissioners. Their daughter Hanne has just joined the criminal division. Their 
youngest son Benjamin has dropped his opposition to the family trade and has just entered the police school. Only their son Sebastian, a photographer, doesn’t want to have anything to do with the cop profession. In the family circle is also the unorthodox Frau Schellenberg, who rents a room from the Krauses.
