Tennis player Jana is found dead in her club's shower. Exactly where her father Volker years ago interrupted her rape by brutally killing the attacker. Volker, who was released early from prison, is suspected because he had argued with his daughter Jana that same evening. When Reuther realizes that Jana had a secret relationship with her rapist, the case takes a whole new turn. Is it a late revenge of the rapist widow Monika Majewski? The competition between the players in the club is also escalating. Does the victim's stepsister, Leonie Dohmke, have her rival on her conscience? But a trail leads to Leonie's mother, Rosalie Dohmke. She had managed the early release of her partner, which is now shaken by Jana's secret.
