In the Gaarden district of Kiel, 60-year-old Onno Steinhaus is found dead. Except for a group of children, nobody seems to have had contact with the neglected man. Klaus Borowski and Sarah Brandt look into an abyss of poverty and indifference when investigating the area surrounding the dead man. Steinhaus had a criminal record for pedophilia. None of the neighbors want to have noticed that children were constantly coming and going and celebrating wild parties. The police officer responsible for the district, Torsten Rauschcapitulated long ago in view of the social neglect of the district. Brandt's investigations brought to light a video showing the boy Timo Scholz in a tricky situation with Onno Steinhaus and also a scene in which Steinhaus was kicked and laughed at by the children.
Was Steinhaus the victim of violent youth? 15-year-old Timo vehemently denies having been abused. Someone else has a secret: Sarah Brandt is conspicuously often looking for closeness to her colleague Torsten Rausch.
