Frederike Bader, a former policewoman from Berlin, currently living in witness protection in Passau, is supposed to help her ex-boss Jochen Mohn - formerly a witness protector, now head of the Passau CID - in a private matter.

Two murders of prostitutes in a similar way - no wonder that Commissioner Sandra Mohr suspects a connection. The obvious suspicion that a serial killer could be up to mischief in Styria is initially dismissed by her supervisor Sascha Bergmann.

Katrin Fischer, a successful businesswoman and participant in a snuggle seminar, is looking forward to an evening tête-à-tête. But instead of romantic hours for two, a bullet in the heart awaits her.

Inspector Bergmann and his new colleague Anni Sulmtaler find themselves dealing with a sinister murder on Halloween of all days. During a session with the medium Vera, a woman is shot through the window. The murder weapon is the husband's hunting rifle. But he can't be the perpetrator.

In order to save her mountain guesthouse from ruin, Sopie plans to build a glass extension with a pool as an attraction. She comes up with this saving idea when her best friend Verena visits, who brings her brother Jan with her and who draws the plans for it.

Pension landlady Sophie imagined her job as mayor differently: not even the garbage collection works anymore! In order to defuse the scandal, she temporarily stores all municipal waste on her own yard. The improvisation artist gets active support from Felix, who appeares virtually with a paraglider out of the blue and skilfully turnes Sophie's head. Just now, Sophie's ex-mother-in-law Brigitte is at the door. The grande dame from Paris wants Sophie to return to her son Phillippe to prevent the unsuitable young successor who, in her opinion, does not come from a good family and only wants to take over the business. While Leonie is happy about her grandmother's visit, Sophie wants to know as little as possible about her. She is amazed at the unexpected magic that the sophisticated Brigitte unleashes on her grumpy barn occupier Barthl. He buys an elegant suit and dresses up neatly to impress the elegant elderly woman. But unfortunately more uninvited guests show up.
