Robert Karow is called to a crime scene. Everything indicates that the young security police officer Rebecca Kästner took her own life in her apartment the night before: drugs, custody dispute, excessive demands. But when Karow finds her four-year-old son Matti in the garden, he has doubts about the suicide. What mother does that in front of her child? Then the last call from the dead to an unusual number: Susanne Bonard, a former LKA great who now teaches at the police academy. She is a luminary whose standard work everyone knows. Before Karow knows it, she is at his side for the investigation in this case. Back on the road again at 62? Bonard was in the process of uncovering right-wing tendencies at her academy, no longer wanted to put up with her director's decreed muzzle and would take action against the dubious teaching methods of her colleague Götz Lennart. During the investigation into Rebecca's death, the detectives also found connections to the right-wing scene, which Bonard quickly suspected was a large right-wing network. Karow thinks that's paranoid. Until he and her have to realize that they are actually confronted with a larger context than initially thought.
