Karow and Rubin investigate the brutal death of a woman active in Berlin's night life.

Everything indicates that the young police officer Rebecca Kästner committed suicide in her apartment the evening before: drugs, custody dispute, excessive demands. But when Karow finds her four-year-old son Matti frightened in the garden, he begins to have doubts about the suicide. What mother does that in front of her child? Then the last call from the dead person was to an unusual number: Susanne Bonard, a former LKA figure 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 to investigate this case. Back on the road at 62?

During the investigation into Rebecca's death, the detectives also come across connections to the right-wing scene, which Bonard quickly suspects is a large right-wing network. Karow thinks that's paranoid. Until he discovers with her that they are actually faced with larger connections than initially thought...
