The ninth crime scene from Franconia, "High Mass for Toni," takes Chief Inspector Felix Voss (Fabian Hinrichs) into his private past. The press release describes that after years of no contact, he receives a surprise call from his old friend Marcus Borchert (Pirmin Sedlmeir), who is now a pastor. Marcus invites Felix to the Sunday sermon to reveal something about Antonia Hentschel, nicknamed Toni. Toni was Felix's great love during his student days in Berlin. But shortly before the service, Marcus is found murdered. Felix learns at the crime scene that Toni committed suicide two years ago.
