Christl Bachmayr was killed in her ceramics shop with a floor vase, the receipts from the cash register are missing. First, her employee Ludwig Reichl is suspected. He had helped himself at the cash register and should therefore be terminated without notice. But also a competitor of the victim Franziska Köhler comes into the focus of the inspectors Stadler and Hansen. The two used to run a ceramics shop together. In the dispute, they ended their business relationship, and Franziska Köhler finally took Christl Bachmayr to court for copyright infringement. When blood is found on a shard of the murder weapon and analyzed, it is clear that it must be a male perpetrator. Will the victim's recovered laptop put the detectives on the right track? While Hansen and Stadler are investigating, there is excitement in the police station: has Commissioner Stadler actually registered on a dating portal? Marie Hofer and Miriam Stockl devise a plan to find out whether Stadler is actually cheating on his wife Hilde on the internet.

Thomas Ritter is found shot dead in the forest by a fellow hunter. But when the police arrive, the body is gone. Did the perpetrator try to cover important tracks? Inspectors Hansen and Stadler decide to treat the matter as murder even without a body. While Michi Mohr directs the search in the forest area, the inspectors investigate the victim's surroundings. His wife Ursula Ritter, however, has a watertight alibi. As it turns out, Thomas Ritter's business conduct also leads to possible motives. The large landowner Claudius von Rentingen was deceived by him and the silent partner Peter Stuber was also deceived. But then coroner Ela Atay comes with new results and an unbelievable suspicion: Isn't Thomas Ritter dead and the whole thing just a staging? The inspectors are about to hand the case over to their colleagues when things take a turn and everything has to be reopened. Meanwhile, caretaker Winkler is taking inventory in the police station and is looking for a technical device that has disappeared but urgently needs to be found. While he is supported by Grasegger and Lange, Eighties and Donato should not find out about the matter. 

Stefan Ertl, workshop manager of the renowned picture frame shop Waasner, is found lifeless by his colleagues. Who surprised him at work at night? Inspectors Stadler and Hansen first try to find out whether it might be a fake burglary. Who could have been interested in harming Ertl and why? Are the suspects to be found in the business environment? The investigators initially targeted Benno Waasner, the owner of the shop, and his wife Elke. Was the business relationship with your employee Ertl really as trusting as you claim? But the entrepreneurial couple Dagmar and Ulrich Kleiber also appear suspicious, because their statement is not consistent and raises questions. Inspector Stadler is not only busy with an exciting case, but also with an order from his wife Hilde. It's the seed fair in Rosenheim and Stadler has to get his wife Hilde a very specific apple tree. This turns out to be more complicated than expected. 

Shortly before the end of their time together in Rosenheim, inspectors Laura and Thomas Schmidt have to deal with a mysterious case: a dead man is found in front of their office door. Who is the man? His papers identify him as a Spanish citizen named José Barthol. But there are doubts as to whether this is his true identity. Mohr also has no further information about the victim this time and Stockl's research comes to nothing. What should she check if it is not clear who you are dealing with? Inspectors Laura and Thomas Schmidt follow the only lead they found on the dead man and come across an accident that happened decades ago. Is the solution to the case really in the past? While the inspectors are investigating, Stockl is supposed to book a room in a boarding house for Thomas Schmidt. He's on vacation soon and wants to go away for a few days. But why does the commissioner need a double room? And for whom is the second opera ticket that Mr. Eighty got him?
